Let us find the points intersections of y2=2x and y=4x−1
⇒(4x−1)2=2x
⇒16x2−10x+1=0
⇒(8x−1)(2x−1)=0
⇒x=21,81
x=21⇒y=4(21)−1=1⇒A(21,1)
x=81⇒y=4(81)−1=2−1⇒B(81,2−1)
A1=∫0812xdx+21×81×21
A1=2[23x23]081+321
A1=241+321sq.units
A2=∫0212xdx−21×1×41
A2=2[23x23]021−81
A2=245sq.units
Therefore, the required area is,
A=241+321+245=329sq.units
