F.IF.1
Understand that a function from one set (called
the domain) to another set (called the range)
assigns to each element of the domain exactly
one element of the range. If f is a function and x
is an element of its domain, then f(x) denotes the
output of f corresponding to the input x. The
graph of f is the graph of the equation y = f(x).
F.IF.2
Use function notation, evaluate functions for
inputs in their domains, and interpret statements
that use function notation in terms of a context.
F.IF.4
For a function that models a relationship
between two quantities, interpret key features of
graphs and tables in terms of the quantities, and
sketch graphs showing key features given a
verbal description of the relationship. Key
features include: intercepts; intervals where the
function is increasing, decreasing, positive, or
negative; relative maximums and minimums;
symmetries; end behavior; and periodicity.★
F.IF.5
Relate the domain of a function to its graph
and, where applicable, to the quantitative
relationship it describes. For example, if the
function h(n) gives the number of personhours it takes to assemble n engines in a
factory, then the positive integers would be
an appropriate domain for the function.*
F.IF.6
Calculate and interpret the average rate of

Identify the effect on the graph of replacing f(x)
by f(x) + k, k f(x), f(kx), and f(x + k) for specific
values of k (both positive and negative); find the
value of k given the graphs. Experiment with
cases and illustrate an explanation of the effects
on the graph using technology. Include
recognizing even and odd functions from their
graphs and algebraic expressions for them.
