Passage: Consider the curves y=x^2 and y=2|x| . Question: What is the area bounded by the curves, the lines x=0 and x=1 ?

Options

  1. A1 square unit
  2. B2 3 square unit
  3. C1 2 square unit
  4. D1 3 square unit

Correct answer

B. 2 3 square unit

Step-by-step solution

For x [0, 1] , the curve y = 2|x| becomes y = 2x . In the interval x [0, 1] , 2x x^2 . The required area is given by the integral: A = ₀¹ (2x - x^2) dx A = [ x^2 - x^3 3 ]₀¹ A = 1 - 1 3 = 2 3 square units.
