Question

If f (x) = one-ninth x minus 2, what is Superscript negative 1 Baseline (x) = one-ninth x + 2 f Superscript negative 1 Baseline (x) = negative 2 x + one-ninth

Answer 1

Answer:

f^-1x=9x+18

Step-by-step explanation:

Answer 2

Answer:

f⁻¹(x)  = 9(x+2)

Step-by-step explanation:

Given the function

f(x) = 1/9 x - 2

We are to find the inverse of the function

Let y = f(x)

y = 1/9 x - 2

Replace y with x

x = 1/9 y - 2

Make y the  subject of the formula

1/9 y = x + 2

Multiply through by 9

y = 9(x+2)

Hence the inverse of the function is 9(x+2)
