Use the function ?(?) = ?4 − 4?3 for questions 12 – 14.
12. Find where ?(?) is increasing and decreasing. Then state the
local maximum and minimum values.
B. Find where ?(?) is concave up and concave down. Then state the inflection points.
C. Find the x- and y- intercepts of ?(?). State any vertical and horizontal asymptotes, if there are any. Then sketch the graph of ?(?) using the information from questions 12 and 13, along with the newly found information. Clearly identify all crucial points and asymptotes.
