Let f(y) be a continuous function:
Suppose that f(-10)>0 and f(10)<0, show that there is a equilibrium point for dy/dt=f(y) between y=-10 and y=10.
Just realized I posted this is in the wrong section, should be in Differential Equations, sorry.

Thanks, I didn't even think to apply that.
The intermediate value theorem states the following: If the function y = f(x) is continuous on the interval [a, b], and u is a number between f(a) and f(b), then there is a c ∈ [a, b] such that f(c) = u.
For anyone else who reads.
