- Find the area of region bounded by generated curves. Do not forget to show your graph. 5. R is the region bounded by y= sqaureroot of x and y=x², where 0 is less than or equal to x is less than or equal to 1.arrow_forward53. The region between the line y=x and the curve y=2x sqrt(1-x^2) in the first quadrant. Find the area.arrow_forwardUse a graphing utility to (a) plot the graphs of the given functions and (b) find the xcoordinates of the points of intersection of the curves. Then find an approximation of the area of the region bounded by the curves using the integration capabilities of the graphing utility. Round answers to two decimal places. y=2x2, y= 5-x4arrow_forward
