Answer:
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
Answer:
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
