Given; g(x)= 8x - 2 what is the value of g⁻¹(30)

(30) = 4

Step-by-step explanation:

g(x) = 8x -2

Let g(x) = y

y = 8x -2  (note: y is the range and x is the domain, we need to rearrange to make x the range and y the domain instead)

y + 2 = 8x

x = (1/8) (y + 2)

hence the inverse of g(x) is (y) = (1/8) (y + 2)

(30) = (1/8) (30 + 2) = 4
