Answer 2

let's try to graph the two functions first

Answer 3

okay

Answer 4

yes always sketch if asked, on same axes,

Answer 6

oh okay so then when it says x=1 , x=1 is that asking for the points ?

Answer 7

No those are telling you the boundaries

Answer 8

I'm pretty sure it's asking for the area between the curves where x = 1 x = -1 are the bounds of integration.

Answer 9

ah okay so then

Answer 10

let me post another image

Answer 11

okie

Answer 12

Answer 13

my guess is that we integrate on the x axis

Answer 14

\[\int\limits_{-1}^{1} (e^{x}-(1+x^{2}))~dx\]

Answer 15

Answer 16

okay so then its that the f(b)- f(a) ?

Answer 17

You always do the upper curve minus lower curve.

e^x rises faster than x^2 + 1 over the interval (and you can verify by sketch)
