### Example

The values –2 and 3 are zeros of the function represented below, since *f*(–2) = 0 and *f*(3) = 0.

### Educational Note

The expression *zero of a function* should not be confused with the expression *solution to an equation*.

In the case of a function *f* defined by the equation *y* = *x*² – 7*x* + 12, the values 3 and 4 are the *zeros of the function* *f* since *f*(3) = *f*(4) = 0.

Also, 3 and 4 are the *solutions to the equation* *x*² – 7*x* + 12 = 0.
