I'm trying to find the area between the curves:
y=x^2 + 4x +1 and
y = 3x+3
A sketch shows me that y =3x+3 is above y=x^2 +4x +1 and I have found the intersection points are x=-2 and x=1.
Does this then mean that I just need to evaluate the integral of (3x+3)-(x^2+4x+1) from -2 to 1?
I know that some of this area lies underneath the x-axis and not sure if I need to be accounting for that or not.
