Question 246 of 401MediumMCQ
Let f(x)=−1+∣x−2∣ and g(x)=1−∣x∣; then the set of all points where f∘g is discontinuous is: Solutions · 1
Official solution
f(g(x))=−1+∣1−∣x∣−2∣=−1+∣−∣x∣−1∣=−1+(∣x∣+1)=∣x∣, which is continuous everywhere. So the set of discontinuity points is empty. Answer the question to unlock
