MediumDetermine concavity and find inflection points (Medium)
18 problems · 25-30 minutes · Skills: derivatives, concavity, calculus
About This Worksheet
This medium-level worksheet contains 18 problems designed for 12th Grade students practicing concavity & inflection points. Medium worksheets introduce larger numbers and varied question formats to deepen understanding and build fluency.
Concavity analysis provides crucial additional information about a function's behavior beyond what the first derivative reveals. In economics, inflection points of a profit function signal the transition from increasing to decreasing marginal returns. In physics, the concavity of position describes whether an object is accelerating or decelerating.
- Determine concavity by analyzing the sign of the second derivative
- Find inflection points where the concavity changes
- Apply the Second Derivative Test to classify critical points as local maxima or minima
- Identify intervals of concavity from a second-derivative sign chart
- Interpret the second derivative as acceleration in a position-velocity-acceleration context
How to Solve: Worked Example
- Read the problem carefully.
- Identify what is being asked.
- Use what you know to find the answer.
- Check your work.
