----------------------------
Use f(x) to find f(x+h)
----------------------------
Compute the difference quotient
----------------------------
The difference quotient is
Now evaluate the limit as h goes to 0. Since we no longer have to worry about division by zero errors, this is the equivalent to plugging in h = 0 to get
----------------------------
So the derivative of f(x) is f ' (x) =
