Question

F(x) = 6x + 4. Find the inverse of f(x).

A. f^-1(x) = 6x - 4

B. f^-1(x) = x-6/4

C. f^-1(x) = 4 - 6x

D. f^-1(x) = x-4/6

Answer 1

D. f-1(x) = x-4/6

Explanation:

y = 6x + 4

-4

y-4 = 6x

÷6

y-4/6 = x

(Swap y and x around to find the inverse)

Inverse will be:

x - 4/6 = y

So, f-1(x) = x-4/6

Hope this helps!
