<PRE><B>Question 142026</B>
This cubic, c(x)=x^3 - 2x^2 - 24x, has zeroes at x = {-2, 0, 6}. What is the value of its local maximum? 
a. -21
b. 21
c. 126
d. This cannot be determined for a cubic since we do not know calculus
-----------------
Graphing shows a local maximum at x = -2.23967 where f(x) = 32.485381...
