The way it changes the graph is that the parabola shifts 3 units down.

Graph of a quadratic function are parabolic in nature. The parent function is given as:

f(x) = x²

If the graph of the function is changed to y= x^2 - 3, this shows that the parent function was shifted down by 3 units.

Hence we can conclude that the way it changes the graph is that the parabola shifts 3 units down.
