Question

The inverse of the function f(x) = { x + 10 is shown.

Answer 1

Answer:

20

Step-by-step explanation:

f(x) = x + 10

Replace f(x) with y.

y = x + 10

Now, remember that in an inverse function you flip the x and y, so

x = y + 10

Solve for y

y = x - 10

because it's 2x... we must multiply by 2.

2y = 2x - 20

Original equation:

h(x) = 2x - 0

h(x) is 2y..
