Hand in your answers to the following four questions:
1.
For the function g(r) = r
3
– 3r
2
– 24r + 5
answer the following (assuming for now that the
variable r can take any value):
a) Determine where the function is concave upward and where it is concave downward.
b)
Find the critical numbers for the function, i.e. where its derivative equals zero.
c)
Use the results of (b) and the Second Derivative Test to determine where the function has a
relative maximum and/or a relative minimum.
d)
If in fact it is only feasible for the variable “r” to be in the range 0 ≤ r ≤ 6, find the absolute
maximum and absolute minimum of the function g(r) in its feasible range.
