Determine the interval of values of $m$ for which the line $y=mx$ and the curve $\displaystyle y = \frac{x}{x^2+1}$ enclose a region. For your answer, use interval notation with no spaces, such as (-1,5) and [9,10). Use MINF for negative infinity and INF for positive infinity if needed.

Interval =

Find the area of the region described above, using $m$ as needed in your answer.

Area of the region =
