Question

anonymous · Answer

A function cannot be a linear function when the function is, for instance,$$F(x)=x^{2}$$You would get a parabola, not a line.  Here's another nonlinear function$$F(x)=x^{3}$$Rule of thumb: a function is linear when x is not raised to a power or when a root has been taken out of it.
