The graph of f(x) is given below. 1. Is f(x) continuous at x = -3? Explain. If Assume each square represents one it is not continuous, identify the type of square unit. discontinuity. 2. Is f(x) continuous at x = 2? Explain. If -x it is not continuous, identify the type of discontinuity. 3. Is f(x) continuous at x = -4? Explain. 4. Is f(x) continuous at x = 4? Explain. If If it is not continuous, identify the type of it is not continuous, identify the type of discontinuity. discontinuity. 5. Determine the value of A such that f(x) is continuous for all real numbers. 2x + 1 f(x) = 2 + Ar +4 x
