Question

what is the inverse of the given relation?
y=3x+12

Answer 1

Here's the process:
1. Interchange x and y (write x where you now see y and y where you now see x).
2. Solve the resulting equation for y.
3. Replace the label y with \[f ^{-1}(x)\]

Answer 2

is it y = x/3 - 4

Answer 3

Yes. Very nice! Don't forget to replace that y with \[f ^{-1}(x).\]

Answer 4
