B.2.1b – Graphical Differentiation Calculus - Santowski
Working Backwards – From f’ to f • You will be given a series of graphs which represent the derivative of a function. • (a) Using the graph of the derivative, state & justify the: • (i) intervals of increase/decrease of f(x) • (ii) extrema of f(x) • (iii) intervals of concavity of f(x) • (iv) inflection points of f(x) • You must then sketch the original function
Working Backwards – From f’ to f • Graph #1
Working Backwards – From f’ to f • Graph #2
Working Backwards – From f’ to f • Graph #3
Inflection Points and Concavities • Describe the concavity of the following graphs and find the points of inflection (if any). You will first do all the work on the TI-89 and then algebraically develop the solutions.
