Multiplicity:The multiplicity of a zero refers to the number of times the zero is repeated as a root of the polynomial function. A simple zero has a multiplicity of one.
Polynomial Function:A polynomial function is a function that can be expressed as the sum of a finite number of nonzero terms, each of which is a product of a constant and one or more variables raised to a nonnegative integer power.
Graphing Polynomial Functions: The graph of a polynomial function is a smooth curve that may have one or more points where the curve crosses the x-axis, known as the zeros or roots of the function.
