What's the inverse of f (x) = 1/3x+2

y = 3x - 6

Step-by-step explanation:

I think you meant f (x) = (1/3) x+2.

1) replace "f (x) " with "y": y = (1/3) x+2

2) interchange x and y: x = (1/3) y + 2

3) solve this result for y. Multiply all three terms by 3: 3x = y + 6. Subtract 6 from both sides, obtaining y = 3x - 6.

4) replace "y" with the symbol for inverse function:

-1

f (x) = 3x - 6

3x-6

Step-by-step explanation:

1. replace x with y

so you get 1/3y+2=x

2. solve whatever you get for y

y=3x-6
