Q. Find the area enclosed by the graphs of f(x)=2−x and g(x)=x2.
Identify Intersection Points: Identify the points of intersection between f(x)=2−x and g(x)=x2. Set 2−x=x2. Rearrange to x2+x−2=0. Factorize: (x+2)(x−1)=0. Solutions: x=−2, x=1.
Set Up Integral for Area: Set up the integral to find the area between the curves from x=−2 to x=1. The area A is given by the integral from −2 to 1 of (2−x−x2)dx.
Calculate Integral for Area: Calculate the integral.A=∫−21(2−x−x2)dx.=[2x−2x2−3x3] from −2 to 1.=(2(1)−(1)2/2−(1)3/3)−(2(−2)−(−2)2/2−(−2)3/3).=(2−1/2−1/3)−(−4−2−(−8/3)).=(3/2−1/3)−(−6+8/3).=(9/6−2/6)−(−18/3+8/3).=7/6−(−10/3).=7/6+10/3.=[2x−2x2−3x3]0.=[2x−2x2−3x3]1.=[2x−2x2−3x3]2.
