Question

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

Answer 1

Y/3=x or y divided by 3 is equals x. They are the same thing just but the equation in word form. 

Answer 2

Answer:

$y=\dfrac{1}{3}x$

Step-by-step explanation:

Given: $y=3x$

We need to find the inverse of given function.

If $y=f(x)$ 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

$x=3y$

Step 2: solve for y

divide both sides by 3

$y=\dfrac{1}{3}x$

Inverse function: $f^{-1}(x)=\dfrac{1}{3}x$

Hence, The inverse function is $y=\dfrac{1}{3}x$
