What is the y - intercept of the graph shown below?

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).

12x + 1 = 25 solve the following equation. then place the correct number in the box provided.
