Use the algebraic tests to check for
symmetry with respect to both axes and the origin.
y = x^4 - x^2 + 3
Let y = - y
-y = x^4 - x^2 + 3
y = (x^4 - x^2 + 3)/-1
y = -x^4 + x^2 - 3
Not symmetric with respect to the x-axis.
Let x = -x
y = (-x)^4 - (-x)^2 + 3
y = x^4 - x^2 + 3
Symmetric with respect to the y-axis.
Let x = -x and y = -y
-y = (-x)^4 - (-x)^2 + 3
y = (x^4 - x^2 + 3)/-1
y = -x^4 + x^2 - 3
Not symmetric with respect to the origin.
