Question

what is the inverse operation of x/3?

or

f(x)= x/3 and the inverse of f(x) is ?

Answer 1

To find the inverse of a function, switch the x and y and then solve for y.

y = x/3 switches to x = y/3.

To solve for y, multiply both sides by 3 to get 3x = y.

The inverse of f(x) = x/3 is f^-1(x) = 3x.
