AP Calculus AB FRQ #4 Explained: 2025 Exam (Non-Calculator)

This video walks step-by-step through Free Response Question 4 from the 2025 AP Calculus AB exam (non-calculator). In this classic AP setup, a function is defined as an accumulation function (a definite integral with a variable upper limit), and we use the Fundamental Theorem of Calculus to analyze its behavior. We interpret the graph, compute areas, and apply the closed interval method to identify an absolute minimum — all with the reasoning expected for full AP credit. 📘 Watch the full 2025 FRQ playlist: 👉    • 2025 AP Calculus AB – Free Response Questi...   Concepts featured in this problem: 🎯 Fundamental Theorem of Calculus 🎯 Accumulation functions 🎯 Interpreting area from a graph 🎯 Derivative of an integral with variable limit 🎯 Absolute extrema on a closed interval 0:00 Problem overview 0:10 Part (a): Calculate the derivative at g'(8) 2:19 Part (b): Find inflection points (and justify!) 5:51 Part (c): Find values of g(x) by computing areas 8:40 Part (d): Closed interval method (candidates test) 15:13 What to do next #APCalculus #APCalcAB #FRQ #2025APExam #CalculusHelp
