Answer:
C. f(x) = x - 7 all over 4
Step-by-step explanation:
NB: Let f(x) = y
Exchange X and Y
Make y the subject
f(x) = 4x + 7
y = 4x + 7
x = 4y + 7
x - 7 = 4y
x - 7 all over 4 = 4 ÷ 4
y = x - 7 all over 4

Step-by-step explanation:
Synthetic division is a useful tool for problems of this sort. (see below)

Another way to work this one is to make use of the remainder theorem. The remainder from division by x+2 will be the value of the function at x=-2 (the value of x that makes the divisor be zero).
(-2)³ -7 = -8 -7 = -15
Only one answer choice shows a remainder of -15, and all agree on the quotient.
