How can you test for X-axis symmetry
|
A function has x-symmetry if, by substituting all y’s for negative y’s, the function reduces back into its original form.
|

|
How can you test for symmetry with respect to the origin?
|
A function has origin symmetry if, by substituting all y’s for negative y’s, and all x’s for
negative x’s, the function reduces back into its original form. |
