Question

Sketch the region enclosed by the given curves and
find its area.

y = x2 ,y = 4x - x2

Expert Solution
Step 1: sketch the graph for the two curves

Calculus homework question answer, step 1, image 1

Let us find the point of intersection by equating the two curves

 x2=4x-x2

x2+x2-4x=0

2x2-4x=0

2x(x-2)=0

2x=0,x-2=0

X=0,x=2

So x varies from 0 to 2.
