Find and simplify the difference quotient f(x+h)-f(x)/h, h can not equal 0 for the given functions.

1. f(x)=x^2+3x+9- I got 2x+h+3

Evaluate the piecewise function at the given value of the independent variable.

2. g(x)={(x^2+2)/x-2 if x can not=2

{x+8 if x=2

Determine g(-5)

my options for the answer are: a. -5, b.3, c.3/7, and d. -27/7

-I got -27/7 and 3 when I solved it, but I dont understand what the question is wanting because -27/7 doesnt equal 2.

3. f(x)={-5x+4 if x<-3

{2x+3 if x > or equal to -3

Determine f(-7)

my answer options: a.39, b.-10, c.42, d.35

-I got 39 and -11 when I solved it and I also dont understand what the question is wanting.
