What is the digit 5 and could you provide an example?

Use the function nest to evaluate p(x) = 1 + x + · · · + x50 at x = 1.00001. (use the matlab ones command to save typing.) find the error of the computation by comparing with the equivalent expression q(x) = (x51 − 1)/(x − 1).

True or false: the graph of y=f(bx) is a horizontal compression of the graph y=f(x) if b< 1
