Algebra 88 - Adding and Subtracting Polynomial Functions

The video tutorial introduces polynomial functions, explaining how they are sums of monomials. It covers the addition and subtraction of polynomial functions, providing examples and graphical representations. The tutorial also explores polynomial functions with multiple variables, demonstrating how to graph them in three dimensions. The video concludes with a preview of the next lecture on multiplying polynomials.

What is the significance of standard form in polynomial functions?

Explain how polynomial functions can have multiple variables.

How does the graph of a two-variable polynomial function differ from a single-variable polynomial function?

What is the result of adding the functions (X + 1)^2 + y^2 and (X - 1)^2 + y^2?
