3. Find the critical numbers:
4. Get the second derivative f":
5. Find the factors: 6. Find the critical numbers:
7. Draw a number line and plot (not to scale) all the critical numbers arranged in as-
cending order:
8. Make the table similar to what is shown below. Create rows for the intervals and
critical numbers.
9. Choose values of c from the intervals:
10. Compute the function values for the critical numbers:
11. Note f'(x) = 0 for x = -},1 and f"(x) = 0 for x = -3,1. Write 0 accordingly.
12. Fill out other values for the column for f' and f". Exact values can be provided but
the SIGNS are already sufficient and more important.
