F(x) = 4x - 9
let f(x) = y, this implies that x = f⁻¹(y)
y = 4x - 9 Let us solve for x.
4x - 9 = y
4x = y + 9
x = (y + 9)/4
Recall that x = f⁻¹(y),
x = (y + 9)/4
f⁻¹(y) = (y + 9)/4
That means that for f⁻¹(x)
f⁻¹(x) = (x + 9)/4
Hope this explains it.
The answer would be y=60.
I think.

Answer:
(x + 2)(x - 4)
Step-by-step explanation:
Given the zeros of a function, say x = a and x = b, then
the factors are (x - a) and (x - b)
From the graph
The zeros are x = - 2 and x = 4, thus the factors are
(x - (- 2)) and (x - 4), that is (x + 2) and (x - 4)
