Finding region bounded by curves

[superelf83]

Hi. I'm new here. :) I was wondering if anyone could help me out with this problem...
i'm supposed to find the region bounded by:
y=x+1
y=e^-x
x=1

i think i should find the other point of intersection but i forgot to do that (i haven't taken a math course for about 4 years).
please help!

It's just

\int_0^1 (x+1-e^{-x}) dx = (\frac 1 2 x^2 + x + e^{-x})\vert_0^1 = 1/2+e^{-1}

Find the region or find the area of the region?

"i think i should find the other point of intersection but i forgot to do that "
Forgot to do that or forgot how to do that?

The region is bounded by the three curves y= x+ 1, y= e^-x and x= 1. It should be easy to see that y= x+ 1 and y= e^-x cross at (0, 1). Of course, y= x+ 1 and x= 1 cross at (1, 2). Finally, y= e^-x and x= 1 cross at (1, e^-1).

maverick6664, please don't give the full answer to homework problems.
