Answer: There are two ways to find maximum profit: with a graph, or with calculus.
Graphically, you’re looking for a global maximum.
A global maximum is the maximum over the entire range of the what is a function. On a graph, that’s the highest peak.
Local maximums happen at inflection points (where the graph changes direction).
At the maximum of a function, the gradient or slope of the function is zero. With calculus, you can find the derivative of the function to find points where the gradient (slope) is zero, but these could be either maxima or minima.
If the slope is increasing at the turning point, it is a minimum.
If the slope is decreasing at the turning point, then you have found a maximum of the function.
