Question

What is the inverse of the function f(x) = 2x - 10?

O h(x) = 2x - 5
O h(x) = 2x + 5
h(x) = =-x-5
N/a
X +

Answer 1

1/2x+5

Explanation:

We can find the answer by doing some simple steps! First, switch the x and y values in the equation. y=2x-10 turns into x=2y-10. Now, all you have to do is solve for y. x+10=2y--> 1/2x+5. So none of the answers are the solution and therefore h(x) = 1/2x+5. Hope that helps!
