Question

Hi I need help with this question

Find the area between the curves
y = 3x^2 + 1 and y = 2x + 2 :
Include a sketch of the curves and the enclosed area.

Answer 1

You have an idea how to do it?

Answer 2

You begin this by finding a intersections of these functions.
You can find it by sketching curves, I guess.

Answer 3

Area between curves is =
\[\int\limits_{a}^{b}f(x)-g(x) dx\]
Make sure f(x) is above / greater than g(x). In this case f(x) should be the line.

a and b are the intersections which you calculate by setting f(x) = b(x) and solving for x.

Answer 4

Ok thanks guys.
