If the degree is even and the leading coefficient is positive, then
f(x) → +∞ as x → –∞
f(x) → +∞ as x → +∞
If the degree is even and the leading coefficient is negative, then

Below is a graph with labeled points. Use the letters to identify key parts of the graph.
You may use a point more than once. You don’t have to use all labeled points.
a) x – intercept(s):________________________
b) local maximum(s): _____________________
c) interval where f(x) is increasing:
(just use the letters)
______________________________________
d) absolute minimum(s) on the interval
from points A to H
______________________________________
e) Does this function have an even or odd degree? Explain.
f) Is the leading coefficient positive or negative? Explain.
