Question

I’d like to check part a and get help with part b

Answer 1

Part A

To graph the inverse function, what you do is to simply switch the x and y-coordinates which was done in your graph.

However, the labelling is incorrect.

• x-axis: Price per toaster (in $)

,

• y-axis: Years since 1960.

Part B

From the first graph:

`\begin{gathered} f(40)=30 \\ \implies f^(-1)(30)=40\text{ years} \end{gathered}`

What the inverse function means is that the toaster's price is $30 in 40 years after 1960.
