<u><em>Answer:</em></u>
D. f⁻¹(x) = 2x + 10
<u><em>Explanation:</em></u>
<u>The given is:</u>
![f(x) = \frac{1}{2}x - 5](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%7B1%7D%7B2%7Dx%20-%205)
<u>To find the inverse, follow the below procedures:</u>
<u>1- Convert f(x) to y. </u>
<u>This will give:</u>
![y = \frac{1}{2} x - 5](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20x%20-%205)
<u>2- Swap the x and y variables.</u>
<u>This will give:</u>
![x = \frac{1}{2}y - 5](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B1%7D%7B2%7Dy%20-%205)
<u>3- Solve for y.</u>
<u>This will give:</u>
![x = \frac{1}{2}y - 5\\ \\ \frac{1}{2}y = x+5\\ \\ y = 2x+10](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B1%7D%7B2%7Dy%20-%205%5C%5C%20%5C%5C%20%5Cfrac%7B1%7D%7B2%7Dy%20%3D%20x%2B5%5C%5C%20%5C%5C%20y%20%3D%202x%2B10)
<u>4- Replace the y in the above step with f⁻¹(x).</u>
<u>This will give us:</u>
f⁻¹(x) = 2x + 10
