Question

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

h(x) = 2x – 5
h(x) = 2x + 5
h(x) = one-halfx – 5
h(x) = one-halfx + 5

Answer 1

Hello

1). Replace f(x) with y.

2). Switch x and y.

3). Solve for y.

f(x)= 2x-10

y= 2x-10

x= 2y-10

x+10 = 2y

x/2 + 5 = y

y = x/2 + 5

Hope that helped!
