Question

Find the area bounded by the curves y = x/2, y = sqrt{x} , and x = 9.

Answer 1

\[y = \frac{ 1 }{ 2 }x \]
\[y = \sqrt{x}\]
\[x = 9\]

i assume it's the shaded region.

so i know it's
\[\int\limits_{0}^{9}\]
but i don't know if the inside is sqrt(x) - x/2 or if its
x/2 - sqrt(x)
plus the dx of course.
