If anyone can help thank you very much! ^^

Answer 1

Answer: LAST OPTION.

Step-by-step 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":

$y+10=2x\\\\\frac{y+10}{2}=x\\\\ x=\frac{1}{2}y+5$

- Exchange the variables:

$y=\frac{1}{2}x+5$

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

 $h(x)=\frac{1}{2}x+5$
