In what areas, other than mathematics, could you expect quadratic equations and functions to be used?.

Functions are so important in mathematics that they will likely be prominent in any subsequent math course you take. Find the indicated outputs of the problems below. Describe more than one way to find the outputs (including graphing calculators and the methods available there).

1) f(p) = 10p; find f(6), f(1/2), and f(20).

2) P(x) = x

^{3}+ x; find P(0), P(-1), P(5).
