    Slope using Diff quotient

    use the difference quotient to calculate the slope of the secant line thru the points (1, f(1)) and (3, f(3))

    #25 f(x)=(x-2)^2

    i assume the difference quotient you're using is: \frac {f(x + h) - f(x)}h

    in that case, the slope of the secant line will be: \frac {f(3) - f(1)}2.

    now continue
