Introduction to Graph Analysis

• Key Advice: Identify the graph type (function, derivative, or another function).
• Recall that slope at a point = value of function’s derivative.
• Area under curve = value of integral.
• Example problem from 2010 AP Calc AB Exam.

Sample Problem Explanation

• Problem Setup: Function G defined, differentiable on [-7, 5], G(0) = 5.
• Graph of G' (G's derivative) given.
• Tasks:
  • Find G(3) and G(-2).
  • Identify points of inflection on G(x).
  • Evaluate critical points of a related function H.

Solving the Problem

• G(3) and G(-2):
  • Calculate using integrals of G' from known value, G(0) = 5.
  • Use geometry concepts (area under curve) for integral evaluation.
• Points of Inflection:
  • Identified by changes in the derivative's behavior (increasing vs. decreasing).
• Critical Points of H:
  • Use derivative definition and solve for critical values.
  • Classification of points using sign changes in derivative.
