Symmetry of a graph Symmetric with respect to the y-axis (even) (x,y) and (-x,y) are both points replace x by –x and yields same equation also all exponents are even Symmetric with respect to the x- axis (x,y) and (x,-y) are both points replace y by –y and yields same equation Symmetric with respect to the origin (odd) (x,y) and (-x,-y) are both points replace x by –x and yields the opposite signed equation also all exponents are odd
