A function symmetrical with respect to the y-axis is called an even function. A function that is symmetrical with respect to the origin is called an odd function. f(x). Since f(−x) = f(x), this function is symmetrical with respect to the y-axis.

Square Root Parent Function: f(x) = √x  

If the graph is symmetrical to the y-axis, the function is even. If the graph is symmetrical to the origin, the function is odd.
