Below

#y=x^2-4#

You will notice straight away that since the #x# is to the power of 2, then it must be a parabola.

A #y=x^2# looks like the graph below

graph{x^2 [-10, 10, -5, 5]}

Now, since the equation has a #-4# attached to it, then all you have to do is to shift your parabola down by 4 units.

Like below:

graph{x^2-4 [-10, 10, -5, 5]}
