PRoblem in Simply Getting the Points of the Intersection and that's the limit of integration. is the Curve Parabola opening upward and a line hitting Q1 Quadrant 2 and 4?Please reply showing what you've tried and how far you've gotten, so we can see exactly where you're having the trouble. Thank you!
Hi, Can u help me? I really need it in the next 15hrs. and i'm still studying for my Physics. Thanks. :sad:Please reply showing what you've tried and how far you've gotten, so we can see exactly where you're having the trouble. Thank you!

Hints:
First plot the functions - using your favorite method .
Next find the points of intersections of y=x^2 & y=8-x
To do that set x^2 = 8-x and solve for 'x' and from there solve for 'y'.

If you are stuck at the beginning tell us and we'll start with the definitions.

Just use what you learned back in algebra: Set equal the two expressions for "y=", and solve the resulting quadratic equation for the x-values of the intersection points. Then plug these back into either of the original equations to find the corresponding y-values.
