Waiting for answer How can you determine the end behavior of a polynomial?
Behavior is dependent on a polynomial's degree. Before anything else, it's important that we're all on the same page about the concept of a polynomial's degree. A polynomial's degree is the degree of its leading term, that is, the largest exponent of ##x## , in most polynomials. For example, the...
