F(x) = 3x + 2 replace f(x) with y

kirill [66]

Answer:

-1 x - 2

f (x) = -----------

Step-by-step explanation:

Then we have y = 3x + 2.

Next, interchange x and y, obtaining x = 3y + 2

Next, solve this result for y: 3y = x - 2; then divide both sides by 3:

y = (x-2)/3

Last, replace "y" with the inverse function label:

-1 x - 2

f (x) = -----------
