given that any function of the form f(x) = x+a/x where a can be any value will have an inverse of the form f-1(x) = a/x-1 find the inverse of the f(x) = x+4/x

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).

The line containing the midpoints of the legs of right triangle abc where a(-5,5), b(1, 1), and c(3, 4) are the vertices.
