MathematicsContinuity and DifferentiabilityJEE Main 2026

Let and g(x)=f(|x|)+|f(x)|. If the number of points where g is not continuous and is not differentiable are α and β respectively, then α+β is equal to .

Answer: 4

Solution

For x≥0, g(x)=2(x²−5x+6) if x≤2 or x≥3, else 0. For x<0, g(x)=x²+5x+6+. At x=0 the two pieces give different values (12 vs 6+1/e),
