Definition
Zeros, also known as roots or x-intercepts, are the values of x for which a function equals zero. In other words, they are the points on the graph where the function crosses the x-axis.
The domain of a function is the set of all possible input values (x-values) for which the function is defined.
Intercepts: Intercepts are points where a graph intersects either the x-axis (x-intercept) or y-axis (y-intercept).
Factors: Factors are expressions that divide evenly into another expression without leaving any remainder. In terms of functions, factors correspond to linear expressions that can be multiplied together to obtain the original polynomial expression.
