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 | * * | | *
