The way I figured this one out was saying that if it takes 2lbs to stretch it to 12 inches and 5lbs to stretch to 18 inches that means that 3 additional pounds = 6 inches. Therefore, each additional pound is 2 inches. We know already that with 2 lbs it was 12 inches in length and we can also say that 2 lbs = 4 inches. So subtract 4 from 12 and you end up with the answer of 8 inches.

I will like to mention that the question is a little obscure, and the explanation applies for the following function:

f(x) = -13x^{5} -4x^{4} -1

You always have to choose the highest power of x, in order to find the leading term.
