Question

what is the inverse of the function f(x)=2x-10 ?​

Answer 1

Answer:

1/2x +5

Step-by-step explanation: Right answer

Answer 2

Answer:

$f^{-1} (x)=\frac{x+10}{2}$

Step-by-step explanation:

$f(x)=2x-10$

$y=2x-10$

$y+10=2x$

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

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

$\frac{x+10}{2}=f^{-1} (x)$
