please show all work to help me better understand.

For each slope below, enter the value correct to four decimal places. Let f(x) = 9.1x7 - 2x. Using the formula, m = f(z + h) f(z) estimate the slope of the tangent h line on the graph of f(x) at a = 3 for the following values of h: helm= h = 0.5: m = h = 0.1: m = h = 0.01: m = h = 0.001: m=
