Step-by-step explanation:</h2>
A function has an inverse function if and only if passes the Horizontal Line Test for Inverse Functions. This test tells us that a function 
has an inverse function if and only if there is no any horizontal line that intersects the graph of at more than one point. So the function is called one-to-one. The graph of 
is shown below. As you can see, this function does not pass the Horizontal Line Test, therefore the inverse is not a function. However, let's find 
:
Finally, substitute 
:
3.33 since we know 12 is for 40 we can set up an equation
