Answer:
A
Step-by-step explanation:
f(3) is another notation for x=3 so what we have to do is find 3 on the x axis and move up or down that line to find the y value
y is 8 units above so
f(3) is 8
Let y be x, and x be y.
x = 4y - 8
Rearrange to make y the subject.
x + 8 = 4y
Therefore
y = (x + 8) / 4
is the inverse.
