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).

Whats the name of the vertical axis

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.
