Which statement best describes the function below

This is a many to one function (answer C). There are multiple x values that yield the same y.

All of the other statements are wrong. It does not fail the vertical line test and it is definately a function.

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
