Problems 39-44
Step 1: First write down the function f.
Step 2: Next, evaluate this function for the value x + h. Simplify this expression.
Step 3: Third, subtract the answer from Step 1 from the answer from Step 2.
Step 4: Finally, divide your answer from Step 3 by h. Factor the numerator,
if possible, and simplify.
This process is shown in Example 4.
