Answer 1

Answer: D

Explanation:

To find the inverse function, you switch y with x and x with y. Then you solve for y.

y=-2x+5 [replace y with x and x with y]

x=-2y+5 [subtract both sides by 5]

x-5=-2y [divide both sides by -2]

(x-5)/-2=y

Now that we have our inverse function, we can rewrite it so that it matches the answer choice. D matches our answer choice the best.
