Answer the following questions. Show all possible solutions on a separate sheet of paper. 1. Determine whether the function f(x) = x2 + 6x +9 is continuous at x= -2. Sketch its graph illustrating its continuity or discontinuity. Solution: Step 1: Evaluate the function f(x) = x2 + 6x + 9 at x = -2 Step 2: Find lim,(x2 + 6x + 9) = _ Step 3: What did you observe between the values of f(-2) and lim f(x) ? Conclusion: Illustrate the graph: V X 2. Is the function f(x) = = continuous on the closed interval [-1, 1] ? Draw its graph illustrating its continuity or discontinuity
