I need help on question 9 I would appreciate it:0

Answer 1

To determine the inverse function, first, we set the following equation:

`y=-10+8x\text{.}`

Now, we solve the above equation for x:

`\begin{gathered} y+10=8x, \\ (y+10)/(8)=x\text{.} \end{gathered}`

Exchanging x and y, we get:

`y=(x+10)/(8)\text{.}`

Finally, we substitute y by

`f^(-1)(x)`

and get:

`f^(-1)(x)=(x+10)/(8)\text{.}`

Answer:

`f^(-1)(x)=(x+10)/(8)\text{.}`
