consider the area between the graphs x+3y=1 and x+9=y^2. this area can be computed in two different ways using integrals. Please integral both ways both respect to x and to y. ANd please show your work and thank you

**Cal**

the question is to find the area. they are two ways either respect to x or respect to y. One way either by doing it to x or to y, your going to end up adding two integrals together to get the answer and the other one the much faster way you only need to compute to integral. My...

consider the area between the graphs x+3y=1 and x+9=y^2. this area can be computed in two different ways using integrals. First of all it can be computed as a sum of two integrals where a=,b=,c= and f(x0= and g(x)=. Alterntaively this area can be computed as a single integral
