A2.3 Families of Functions (linear, quadratic,
polynomial, rational, power, exponential,
logarithmic, and trigonometric)
A2.3.1 Identify a function as a member of a family of
functions based on its symbolic, or graphical
representation; recognize that different families of
functions have different asymptotic behavior at
infinity, and describe these behaviors.
A2.3.2 Describe the tabular pattern associated with
functions having constant rate of change (linear); or
variable rates of change.
A2.3.3 Write the general symbolic forms that
characterize each family of functions. e.g., f (x ) =
A0ax ; f (x ) = AsinBx.
A2.4 Lines and Linear Functions          
A2.4.1 Write the symbolic forms of linear functions

and slope-intercept) given appropriate
information, and convert between forms.

h and y = k ) given appropriate information.
A2.4.3 Relate the coefficients in a linear function to
the slope and x - and y -intercepts of its graph.
A2.4.4 Find an equation of the line parallel or
perpendicular to given line, through a given point;

parallel lines have equal slopes, and that non-vertical
perpendicular lines have slopes that multiply to give -
A2.5 Exponential and Logarithmic Functions          
A2.5.1 Write the symbolic form and sketch the graph

A2.5.2 Interpret the symbolic forms and recognize
the graphs of exponential and logarithmic functions
(e.g., f (x ) = 10 x , f (x ) = log x , f (x ) = ex , f (x ) = ln
x ); recognize the logarithmic function as the inverse
of the exponential function.
A2.5.3 Apply properties of exponential and
logarithmic functions (e.g., ax+y = axa y ; log(ab )=
log a + log b ).
A2.5.4 Understand and use the fact that the base of
an exponential function determines whether the
function increases or decreases and understand how
the base affects the rate of growth or decay.

to real phenomena , including half-life and doubling

A2.7.2 Express direct and inverse relationships as

coefficient, and number of real zeros on the graphs

A2.10 Trigonometric Functions          
A2.10.1 Use the unit circle to define sine and cosine;
approximate values of sine and cosine (e.g., sin 3 ,
or cos 0.5 ); use sine and cosine to define the
remaining trigonometric functions; explain why the
trigonometric functions are periodic.
A2.10.2 Use the relationship between degree and
radian measures to solve problems.

trigonometric functions (involving changes in period,
amplitude, and midline) and understand the
relationship between constants in the formula and
the transformed
Students construct or select a function to model a
real-world situation in order to solve applied
problems. They draw on their knowledge of families
of functions to do so.
A3.1 Models of Real-world Situations Using
Families of Functions.

Example: An initial population of 300 people grows at
2% per year. What will the population be in 10 years?
A3.1.1 Identify the family of function best suited for
modeling a given real-world situation (e.g., quadratic
functions for motion of an object under the force of
gravity; exponential functions for compound interest;
trigonometric functions for periodic phenomena. In
the example above, recognize that the appropriate
general function is exponential (P = P0at )
A3.1.2 Adapt the general symbolic form of a function
to one that fits the specifications of a given situation
by using the information to replace arbitrary
constants with numbers. In the example above,
substitute the given values P0 = 300 and a = 1.02 to
obtain P = 300(1.02)t .
A3.1.3 Using the adapted general symbolic form,
draw reasonable conclusions about the situation
being modeled. In the example above, the exact
solution is 365.698, but for this problem an
appropriate approximation is 365.
