# Points, Vectors, and Functions

### Example 1

By comparing the values *f*(*x*) and *f*(*-x*), determine whether each function is (a) even or (b) odd. Use a graphing calculator to check your answer.

*f*(*x*) = 6

### Example 2

By comparing the values *f*(*x*) and *f*(*-x*), determine whether each function is (a) even or (b) odd. Use a graphing calculator to check your answer.

*f*(*x*) = -x

### Example 3

By comparing the values *f*(*x*) and *f*(*-x*), determine whether each function is (a) even or (b) odd. Use a graphing calculator to check your answer.

*f*(*x*) =*x*^{3}+*x*^{4}

### Example 4

*f*(*x*) and *f*(*-x*), determine whether each function is (a) even or (b) odd. Use a graphing calculator to check your answer.

*f*(*x*) = 0
