Suppose that the piecewise function f is defined by x + 3, f(x) = { -4x²+x+7, Determine which of the following statements are true. Select the correct answer below: f(x) is not continuous at x = 1 because it is not defined at x 1. O O x < 1 x > 1° = f(1) exists, but f(x) is not continuous at x = 1 because lim f(x) does not exist. x→1 ƒ(1) and lim f(x) both exist, but f(x) is x→1 O not continuous at x = 1 because lim f(x) = f(1). x-1 O f(x) is continuous at a = 1.
