Steps:</h2>
Here are the steps to convert an equation to its inverse:
- Change f(x) to y
- Switch the positions of x and y
- Solve for y
- Change y to f^-1(x)
Firstly, do the first two steps:

Next, let's solve for y. Subtract 3 on both sides:

Next, divide both sides by 4:

<h2>Answer:</h2>
Finally, change y to f^-1(x) and your final answer will be:
, or <u>the second option.</u>
