Instructions: For each of the following functions: Find and classify all the "Critical Points" of the function; also find the y-values of all critical points. Refer to the detailed procedure provided in Module #7 - for finding, evaluating, classifying, and interpreting the critical points of a function using the "Second Derivative Test". Make sure you factor correctly and avoid algebra errors. Show All Work! (Attach extra sheet as needed)

1) f(x) = x³ -2x² -4x + 5

2) f(x) = 3x⁴ - 12x³ - 1
