Question

Find the inverse f(x)=x-11

Answer 1

`f^-^1(x) = x+11`

Explanation:

- Write as an equation.

y = x - 11

- Interchange the variables.

x = y - 11

- Solve for y

y = x + 11

- Replace the y with
`f^-^1(x)` to show the final answer.

`f^-^1(x) = x+11`

hope this helps :)

Answer 2

f(x)=x+1/11

Explanation:

These two lines would be perpendicular.
