a. Algebraically compute the secant slope or for the parabola with equation f(x) = 9-x2. The value of the secant slope when h goes to zero, if it exists, is the slope of the tangent line to a function f (or the derivative of f) b. Evaluate your algebraic formula for the slope of the tangent line at the table values: ................
