Bounding function

70 Views Asked by At

I am trying to work on a function of the form $\frac{x^{2}}{(x+y)^{2}}$ near the origin, however the limit of this function is indeterminate. Is anyone aware of any function which bounds this above for $x,y\geq 0$? This is in relation to steady state equilbria stability in a system of ODE's.
