Which of the following is the inverse of y=3x

Step-by-step explanation:

Given:

We need to find the inverse of given function.

If is a function then inverse [/tex] x=f^{-1}(x)[/tex]

Inverse function is symmetry about the line y=x

Step 1: switch x and y

Step 2: solve for y

divide both sides by 3

Inverse function:

Hence, The inverse function is

47 - 90 = 43

43 - 180 = x

x = 137
