What is the definition of Zeros, Roots, and Solutions?

• Any point where y is 0, also know as x-intercepts.

• the point of intersection of lines or the point opposite the base of a figure

• When the arrows point down and your a-value is negative.

• All of your x-values. For parabolas, it is all real numbers UNLESS it is a real world example.
