A-REI.D.10
F-IF.A.1
Graphing
Families of
Functions
Understand that the graph of an
equation in two variables is the set of all its solutions plotted
in the coordinate plane, often forming a curve (which could
be a line).
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.A.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.B.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
functions is increasing, decreasing, positive, or negative;
relative maxima and minima; symmetries; end behavior; and
periodicity.
F-IF.B.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 person-hours it takes to assemble n engines in a factory,
then the positive integers would be an appropriate domain
for the function.
