Which of the following is the inverse

Given function is f(x) = 9x or y = 9x.

First step is to find the inverse is switch x and y. Therefore, the above equation will be:

x = 9y.

Next step is to solve the equation for y to get the inverse of f(x). So, divide each sides by 9 to isolate y. Hence,

y =

So, the correct choice is A:

ddsf

step-by-step explanation:

dfs

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
