Suppose you went on vacation but forgot your smart phone charging cable. Your phone battery died after two full days(48 hours) of use. This situation is modeled by the equation f(h) =48-h/48, where h is the hours of cell phone use and f(h) is the percentage of battery life left. What is the upper bound of the parameter h? what is the lower bound?

definitely a. the others have almost all data points on one side of the line.

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
