The equation 25 = x^2 + y^2 is a nonlinear equation because it contains terms with squared variables. It describes a circle with a radius of 5 centered at the origin.
As for being a function, it is not a function because for each x-value, there can be multiple y-values that satisfy the equation. In other words, there are infinite y-values corresponding to a single x-value.
