Activity 2: Graphical approach to evaluating limits Thus far you have evaluated limits using a numerical approach. In the activities that follow you will evaluate functions using their graphical representations. 2.1 Study the following four graphs. 8(1) h(x) -2.5 -1.5 -0.5 0 0.5 1.5 2 2.5 'j(x)' Use the intuitive definition of a limit and the geometric representations of functions f(x), g(x), h(x) and j(x) to evaluate 2.1.1 lim f(x) 0 Activity 2: Graphical approach to evaluating limits Thus far you have evaluated limits using a numerical approach.
