The function f(x)=∣x∣+∣x∣xf(x) = |x| + \frac{|x|}{x} is (a) Continuous at the origin (b) Discontinuous at the origin because ∣x∣|x| is discontinuous there (c) Discontinuous at the origin because ∣x∣x\frac{|x|}{x} is discontinuous there (d) Discontinuous at the origin because both ∣x∣|x| and ∣x∣x\frac{|x|}{x} are discontinuous there
