Thread: Area between the graphs

ok i got the parts where there is a number in the field but im way confused on what it wants for the other ones. Can you help?


Consider the area between the graphs and . This area can be computed in two different ways using integrals.

First of all it can be computed as a sum of two integrals

with the following values:






Alternatively this area can be computed as a single integral

with the following values:




Either way we find that the area is .

check this. did you really mean to type 1y like that?

its an online assignment so i just copied it straight from there and that is how they have it. I'm not sure why but they do

i will say this. the area between two curves is given by or

so draw the two curves and see what these functions are and the limits of integration they carry

k i got all the information on the first part, but then on the second part i only have the bottom limit of the integral which is -5 but idk wat the top limit is. Cuz i tried 11 and 20 and those dont work and idk wat else it could be

you had to solve

oh ok i get it now. thanks
