Hello, William!
It seems straight-forward ... Where is your difficulty?
1. Describe the graph of under:
a) - and -intercepts
b) end behaviors
c) local maximum points
d) local minimum points
(a) For -intercepts, let
. . . .
. . For -intercepts, let
. . . .
(b) When
. . .When
. . .The graph "goes down" at both ends.
. . .It is shaped like an
(c) (d) For extreme points, solve
We have: .
Factor: .
. . and we have: .
There is a minimum at and maximums at
The graph looks like this:Code:| * | * |* * | * * * | * * * | * * * ---*---------+----------*---------------*---- -3 | 3 4 | * * | | *
