just replace the value in the appropriate equation:

a) says f(-2)

 so use the f equation above it and replace x with -2

f(x) = 3x-5 becomes f(-2) = 3x-5 =

3(-2)-5 = -6-5 = -11


 for b use the equation for h and replace x with -5

so x^2 - 6 = -5^2 - 6 = -31


 for c use the equation for g and replace x with (a+b)

-7x+3 =

-7(a+b)+3 = -7a-7b+3
