The $$\Delta$$symbol means take the difference between successive values of ...

So $$\Delta f(x)$$means take the difference between successive values of f(x): namely 3 here, and $$\Delta x$$means take the difference between successive values of x, or 1 here.

So $$\frac{\Delta f(x)}{\Delta x}=\frac{3}{1}\rightarrow3$$
