Graph linear and quadratic functions and identify intercepts, maxima, and minima.

Interpret an x-intercept, y-intercept, maximum, or minimum of a linear or quadratic graph in context

Problem

The graph shows profit \(P\) in dollars versus quantity \(q\) in items and marks the maximum \((20,500)\). State what each coordinate means with units, distinguish the input quantity from the output profit, and give the complete contextual interpretation of the maximum.
