Question

For this question.I am confused for some reason. 

1) How can we determine which graph is higher? which one is lower? (like which integral minus which integral, how do you tell?)

2) how do you find the intercept? It is very hard for me to solve e^x = x^2 -1. Can you show me the details? 

 

Sketch the region enclosed by the given curves. Decide
whether to integrate with respect to x or y. Draw a typical approxi-
mating rectangle and label its height and width. Then find the area
of the region.
5. y = e*, y = x² – 1, x = -1, x= 1
