How do you determine the distance between zeros of a polynomial?

Back

To find the distance between zeros, calculate the absolute difference between the zeros. For example, if the zeros are x1 and x2, the distance is |x1 - x2|.

What does it mean for a function to be negative on an interval?

Back

A function is negative on an interval if its output values (y-values) are less than zero for all x-values in that interval.

What is the significance of complex zeros in polynomial functions?

Back

Complex zeros occur in conjugate pairs and indicate that the polynomial does not cross the x-axis at those points. For example, if a polynomial has a zero of 4+i, it also has a zero of 4-i.
