F(x)=2x+7,, find f^-1(f(f^-1(9)))

If the original function is f(x)=2x-7, the order for the function is to multiply the x by 2 and then subtract 7. The inverse reverses this, so it adds 7 to the y and then divides by 2. So, the inverse of f(x)=2X-7 is f^-1(y)=(y+7)/2.

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
