Course Number: 411500CW
In South Carolina College- and Career-Ready (SCCCR) Algebra 2, students extend their study of foundational algebraic concepts, such as linear functions, equations and inequalities, quadratic functions, absolute value functions, and exponential functions, from previous mathematics encounters. Additionally, students study new families of functions that are also essential for subsequent mathematical application and learning. Students are expected to apply mathematics in meaningful ways to solve problems that arise in the workplace, society, and everyday life through the process of modeling. Mathematical modeling involves creating appropriate equations, graphs, functions, or other mathematical representations to analyze real-world situations and answer questions. Use of technological tools, such as hand-held graphing calculators, is important in creating and analyzing mathematical representations used in the modeling process and should be used during instruction and assessment.

Creating Equations
The student will:

quantities. Graph the equations on coordinate axes using appropriate labels,
units, and scales.
A2.ACE.3 Use systems of equations and inequalities to represent constraints arising in
real- world situations. Solve such systems using graphical and analytical
methods, including linear programing. Interpret the solution within the context

completing the square, the quadratic formula and factoring, as
appropriate to the initial form of the equation. Recognize when the
quadratic formula gives complex solutions and write them as a+ bi for
real numbers a and b .
(Note: A2.AREI.4b is not a Graduation Standard.)
A2.AREI.7 Solve a simple system consisting of a linear equation and a quadratic equation
in two variables algebraically and graphically. Understand that such systems
may have zero, one, two, or infinitely many solutions. (Limit to linear equations
and quadratic functions.)
A2.AREI.11* Solve an equation of the form f(x) = g(x) graphically by identifying the x
-coordinate(s) of the point(s) of intersection of the graphs of y = f(x) and
y = g(x) .
Structure and Expressions
The student will:
A2.ASE.1* Interpret the meanings of coefficients, factors, terms, and expressions based
on their real-world contexts. Interpret complicated expressions as being
composed of simpler expressions.
A2.ASE.2* Analyze the structure of binomials, trinomials, and other polynomials in order
to rewrite equivalent expressions.
A2.ASE.3* Choose and produce an equivalent form of an expression to reveal and explain
properties of the quantity represented by the expression.

b. Determine the maximum or minimum value of a quadratic
function by completing the square.
c. Use the properties of exponents to transform expressions for
exponential functions.
Building Functions
The student will:
A2.FBF.1* Write a function that describes a relationship between two quantities. (Note:
IA.FBF.1a is not a Graduation Standard.)
a. Write a function that models a relationship between two
quantities using both explicit expressions and a recursive process
and by combining standard forms using addition, subtraction,
multiplication and division to build new functions.
b. Combine functions using the operations addition, subtraction,
multiplication, and division to build new functions that describe the
relationship between two quantities in mathematical and real-world
situations.
A2.FBF.2* Write arithmetic and geometric sequences both recursively and with an explicit
formula, use them to model situations, and translate between the two forms.
A2.FBF.3* Describe the effect of the transformations kf(x), f(x) + k, f(x + k), and
combinations of such transformations on the graph of y = f(x) for any real
number k . Find the value of k given the graphs and write the equation of a
transformed parent function given its graph.
Interpreting Functions
The student will:
A2.FIF.3* Define functions recursively and recognize that sequences are functions,
sometimes defined recursively, whose domain is a subset of the integers.
A2.FIF.4* Interpret key features of a function that models the relationship between two
quantities when given in graphical or tabular form. Sketch the graph of a
function from a verbal description showing key features. Key features include
intercepts; intervals where the function is increasing, decreasing, constant,
positive, or negative; relative maximums and minimums; symmetries; end
behavior and periodicity.
A2.FIF.5* Relate the domain and range of a function to its graph and, where applicable,
to the quantitative relationship it describes.
A2.FIF.6* Given a function in graphical, symbolic, or tabular form, determine the average
rate of change of the function over a specified interval. Interpret the meaning
of the average rate of change in a given context.
A2.FIF.7* Graph functions from their symbolic representations. Indicate key features
including intercepts; intervals where the function is increasing, decreasing,
positive, or negative; relative maximums and minimums; symmetries; end
behavior and periodicity. Graph simple cases by hand and use technology for
complicated cases.
a. Graph rational functions, identifying zeros and asymptotes when
suitable factorizations are available, and showing end behavior.
b. Graph radical functions over their domain show end behavior.
c. Graph exponential showing intercepts and end behavior.
A2.FIF.8* Translate between different but equivalent forms of a function equation to
reveal and explain different properties of the function. (Note: A2.FIF.8b is not a
Graduation Standard.)
b. Interpret expressions for exponential functions by using the properties
of exponents.
A2.FIF.9* Compare properties of two functions given in different representations such as
algebraic, graphical, tabular, or verbal.
Linear, Quadratic, and Exponential
The student will:
A2.FLQE.1* Distinguish between situations that can be modeled with linear functions or
exponential functions by recognizing situations in which one quantity changes
at a constant rate per unit interval as opposed to those in which a quantity
changes by a constant percent rate per unit interval. (Note: A2.FLQE.1b is not
a Graduation Standard.)
b. Recognize situations in which a quantity grows or decays by a
constant percent rate per unit interval relative to another.
A2.FLQE.2* Create symbolic representations of linear and exponential functions, including
arithmetic and geometric sequences, given graphs, verbal descriptions, and
tables.
A2.FLQE.5* Interpret the parameters in a linear or exponential function in terms of the
context.
