Assume each square represents one If it is not continuous, identify the type of square unit. discontinuity. 2. Is f(x) continuous at x = 2? Explain. If 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. f(@) = 2x+1 2 + Ar +4 2 31 Determine whether each function is continuous at the given point. Explain. 6. f(2) = 5x -4 x2 2 x2 + 2x - 2 x
