F

Let's say you have a function, call it $\displaystyle y=f(x)$. This is any ol' function, not necessarily a parabola. Could be a straight line, could be a parabola, could be a sine wave, etc. Let's say it has a "root" at $\displaystyle x=3.$ Graphically, what is happening to $\displaystyle f(x)$ at $\displaystyle x=3$?
