What is the inverse of f(x)=4x+3 ?
GaryK [48]
<h2>Steps:</h2>

Here are the steps to convert an equation to its inverse:

  1. Change f(x) to y
  2. Switch the positions of x and y
  3. Solve for y
  4. Change y to f^-1(x)

Firstly, do the first two steps:

x=4y+3

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

x-3=4y

Next, divide both sides by 4:

\frac{1}{4}x-\frac{3}{4}=y

<h2>Answer:</h2>

Finally, change y to f^-1(x) and your final answer will be:

f^{-1}(x)=\frac{1}{4}x-\frac{3}{4} , or <u>the second option.</u>
