What is the answer for?
Problem 1
Only answer True when the statement is ALWAYS True.
The function f(x) = e power of x / (x squared − 1) is continuous on [2, 5].
Problem 2
If log(x) = 4 then log(x^2) is ....
Problem 3
log base 2 (3x) + log base 2 (2x) = 3, what is x?

Test the application of derivatives
A small company makes x hand-painted tiles daily at a cost of C(x) = 125 + 30x + 2x^3/2
dollars. What daily production level minimizes the average cost—i.e., the cost per tile?
