Area bounded by the x-axis
If asked to find an area bounded by the $x$-axis, what should you be careful of?
Making sure the integral is not negative.
If the curve was $f(x)$ and the roots were $a$ and $-a$, how would you find the area bounded by the $x$-axis and the curve?
If the curve was $f(x)$ and the roots were $a$ and $-a$, how would you find the area bounded by the $x$-axis and the curve?
\[ \vert \int^a _ {-a} f(x) \text{d}x \vert \]
