# Finding minimum potential

If we have a particle of mass m moving in the presence of the following potential in one dimension:

V(x) = V0 [(e-2$$\gamma$$x) - 2e-$$\gamma$$x)]

In order to find the minimum of the potential V do we take the derivative with respect to x?

dV(x)/dx = 2*$$\gamma$$V0[(e-$$\gamma$$x) - (e-2$$\gamma$$x)]

Is this how we find the minimum potential of V?

And how do we sketch a graph of V?

A point can only be a minimum of a function if the derivative at that point equals what?

zero?
