For the function f defined by f(x)=3x+4 9x-2 I know that for a I substitute x with -2. I just don't know how to solve b,c, & d. The letters are throwing me off. a. f(-2)= b. f(-x)= c. -f(x)= d. f(x+h)=

9x-2 is supposed to be under 3x+4

The letters are throwing me off. a. f(-2)= b. f(-x)= c. -f(x)= d. f(x+h)= (b) just replace x with -x like how you did for -2 (c) (d)replace x with x+h

Stapel, I got it now. Thanks!
