itself. Even Functions
If f(-x) = f(x) for every value in its domain,
then the function is an even function.
then Even axis. functions are symmetric to the y- Odd Functions
If f(-x) = -f(x) for every value in its domain,
then it is said to be an odd function.
odd Odd functions are symmetric to the origin. A graph is symmetric to the x-axis if every
