If anyone can help thank you very much! ^^

Answer 1

Answer: LAST OPTION.

Explanation:

Given the function f(x):

`f(x)=2x-10`

You can follow these steps in order to find its inverse function h(x):

- Rewrite it with
`f(x)=y`:

`y=2x-10`

- Solve for "x":

`y+10=2x\\\\(y+10)/(2)=x\\\\ x=(1)/(2)y+5`

- Exchange the variables:

`y=(1)/(2)x+5`

- Rewrite it with
`y=h(x)`. Then:

`h(x)=(1)/(2)x+5`
