Having trouble getting the answers to these questions...
If f and g are differentiable increasing functions and g(x) is never equal to 0, then the function h(x) = f(x)/g(x) is also a differentiable increasing function.
If a function is period with period c, then so is its derivative.
If C(q) represents the cost of producing a quantity q of good, then C'(0) represents the fixed costs.
Thanks!
