Question

What is the inverse of the function f(x) = x + 2? h(x) = 18x – 2 h(x) = 9x – 18 h(x) = 9x + 18 h(x) = 18x + 2

Answer 1

Thank you for asking this question:

f(x) = 1/9 x + 2

y = 1/9 x + 2

x = 1/9y + 2

x - 2 = 1/9 y  | -9

y =  9x - 18

h(x) = 9x - 18

So the correct answer for this question is option B h(x) = 9x – 18
