## Suggestion

Find the coordinates of the turning points on the curve with equation $y=\frac{x^2}{1+x^4}.$

What do we know about the derivative of a function at a turning point?

Do we know any rules for differentiating functions like this one?

Sketch the curve.

What does the curve look like for large values of $x$?
