Can someone teach me symmetry in algebra 2

In general terms, a graph in two-dimensions is said to be symmetric about a particular line if the portion of the graph on one side of the line is a mirror image of the portion of the graph that is on the other side of the line.

OR:

These are functions/formulas that when drawn in a graph the will be symmetric. Take the classic f(x)=x² f(2)=4 and f(-2)=4 too, when you draw this equation you will get a parabola.
