Interpret key features of rational, square-root, cube-root, and other function models in context.
Match a context question to the graph feature that answers it
Problem
State the graph feature of a profit or difference model that gives the production level where the business breaks even.
Big Picture
What this problem is really about
Start by translating the business question into an output condition before naming any graph feature. Break-even means the difference between revenue and cost has become zero, so look for where that model lies on the axis representing zero output. The corresponding input coordinate supplies the production level the question asks about.
