Answer:
40 degrees is (40/360)=0.111=11.1%
The color closest to 11.1% is Purple at 12%.
The total who prefer a rainbow color is:
13+4+5+15+16+12=65

Determine the inverse function

Replace f(x) with y

Swap the positions of x and y

Multiply both sides by -2


Square both sides


Make y the subject

The inverse has been solved. So, we need to replace y with f'(x)

Next, is to determine the interval

Change inequality to 

Hence, the inverse function is:
