5. [ 6] (a) For the function shown in Figure below, determine the one-sided limits at the points of discontinuity. (b) Which of these discontinuities is removable and how should f be redefined to make it continuous at this point? 6. [6] Let x2 +3 for x 2 Note: do not use the graph of fix) to answer parts a). (e compute the right- and left-hand limits at x = 1 and 2, and determine whether f (x) is left-continuous, right-continuous, or continuous at these points. b) Confirm your answers with the sketch of f(x)
