1. Consider the functions: f(x)=x2−15, g(x)=x−−√ and h(x)=2x What order must the functions be placed in so that an initial input of x=3
gives a final output of 7?

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
