Review Notes for Calculus I Symmetry:  A graph is symmetric with respect to the y-axis if whenever (x, y) is a point on the graph then (-x, y) is also a point on the graph. Some even functions (y=x , y=x , etc.) have symmetry with respect to the y-axis. These graphs usually are parabolas (u-shaped graphs). To figure out if a graph has y-axis symmetry, then you replace all x’s with the opposite of x (ex: x would become –x).  A graph is symmetric with respect to the x-axis if whenever (x, y) is a point on the graph then (x, -y) is also a point on the graph. These graphs can look like a parabola turned on its side. To figure out if a graph has x-axis symmetry, you replace all y’s with the opposite of y (ex: y wo
