since the graph is symmetrical over the y-axis, work in quad I
determine the area,
now, set and solve for .
I need to find the number b such that the line y=b divides the region bounded by the curves y=x^2 and y=4 evenly. I know it will be larger than 2 obviously, however I can't seem to figure out how to approach the problem. Any help would be much appreciated.
