The Difference (or Newton) Quotient

 Description Evaluate the difference (or Newton) quotient.

 The Difference (or Newton) Quotient $\frac{f\left(a+h\right)-f\left(a\right)}{h}$ Enter the function $f\left(x\right)$ to be evaluated, the $x$-coordinate of the point of tangency, $a$, and $h$, where $a+h$ is the   $x$-coordinate of the point at which the secant line will be found.  $a=$ $h=$
