You can put this solution on YOUR website! Find the area enclosed by the curve, y=25- x^2 and the straight line, y=x+13
-------------
The 2 points of intersection are at x = -4 and x = 3.
y=25- x^2
INT(x) = 25x - x^3/3
INT(3) = 75 - 9 = 66
INT(-4) = -100 + 64/3 = -236/3
Area under parabola to x-axis = 66 + 236/3 = 434/3
-------------
Area under line = 87.5
--> 343/6 sq units
