What does it mean if a function has no zeros?

Back

If a function has no zeros, it means that there are no values of x for which the function equals zero.

Front

What is the relationship between the zeros of a function and its graph?

Back

The zeros of a function correspond to the x-intercepts of its graph, where the graph crosses the x-axis.

How can you verify if a number is a zero of a function?

Back

To verify if a number is a zero, substitute it into the function. If the result is zero, then it is a zero of the function.
