Posted by jasmineT on Saturday, April 28, 2012 at 6:48pm.

Can someone look at my work and see what i did wrong. I did this 100 times but i keep getting it wrong

Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Then find the area of the region.
2y=3x^(1/2) , y=4 and 2y+1x=4

y=3(x^(1/2))/2, y=4 , y=2-(1/2)x
Intersection points = -4,1,64/9
Integral from -4 to 1
4x-2x-(x^2)/4
Integral from 1 to 64/9
4x-3(x^(5/2))/5

please help i've been working on this for hours
