Answer 8

x is the length. Since you can't have a negative length or a zero length, x has to be greater then zero. So that leaves out the first two answers.

y is the area. You can't have a negative area. So looking at the graph, the y value (area) dips into the negative area between x=0 and x = 2. So the third answer is wrong.

This leaves the last answer as being the correct one, since the length is positive value and the area is a positive value when x is greater than 2.
