For Steve:

I need your help with the following problems.

(1) In the following exercise, find the x- and y- intercepts of the graph of the equation. (If there is more than one of either intercept, enter the smaller value first. Enter NONE in any unused answer blanks.)

y = x2 + 2x − 8

(2) Perform the indicated operations and simplify your answer.

x 1

_________ - _____

x^2 +3x -28 x + 7

(3) Consider the following functions.

f(x) = x2 + 7

g(x) = √9 – x

Find g(f(x)), if defined. (If an answer is undefined, enter UNDEFINED.)

(4) Simplify the expression by factoring.

4x(x– 1)9/2 – 8(x– 1)7/2
