Given f(x)=1/x−3 and g(x)=9/x−1, find the domain of f(g(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).

Select the quadratic that has root x = 8 and x = -5

The suare root of 9x plus 7 plus the square rot of 2x equall to 7
