MAT.126 P.1 Graphs and Models

Test a graph for symmetry with respect to an axis and the origin

Intercepts + Symmetry
Polynomials

wrt y-axis if each term has an even exponent (a constant has exponent zero so is even)

wrt origin if each term has an odd exponent

wrt origin

Whenever (x,y) is a point on the graph, (-x,-y) is also a point on the graph.

Replacing x by -x and y by -y yields an equivalent equation.

wrt x-axis

Whenever (x,y) is a point on the graph, (x,-y) is also a point on the graph.

Replacing y by -y yields an equivalent equation.

wrt y-axis

Whenever (x,y) is a point on the graph, (-x,y) is also a point on the graph.

Replacing x by -x yields an equivalent equation.
