Question

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

Answer 1

h(x) = 2x + 5

Explanation:

To find the inverse, interchage the variables and solve for y

Answer 2

1/2x+5

Explanation:

y = 2x-10

Exchange x and y

x = 2y -10

Solve for y

x + 10 = 2y-10+10

x+10 = 2y

Divide by 2

x/2 + 10/2 = 2y/2

1/2x +5 = y

The inverse is 1/2x+5
