3. The graph of y = f(x) is shown. Analyse the graph to determine, where applicable, intervals of increase and decrease, local extrema, points of inflection, intervals of concavity and type of function. Draw a graph of y = f'(x)on the graph (on the right) in a different colour.. For f(x): The intervals of increase are: The intervals of decrease are: The extrema is: (state both the min and max) Points of inflections occur at Concavity: concave up occurs at this interval: concave down occurs at this interval: Type of function: 15 y = f(x) {-1.8) VA X
