21. Given y = x2 – [x] – 6. Determine whether it is an odd function or even function and graph the function.

To determine if the function is even or odd, use the appropriate notation

Substitute -x for x

A negative base raised to an even power equals a positiveWhen there is a - in front of an expression in parentheses, change the sign of each term in the expression

Since neither f(-x)=f(x) nor f(-x)=-f(x) are true statements, the function is neither even nor odd

Neither even nor odd..~

Graph is attached with details!!~

What am i doing here. add?
