Topic 1.6: Polynomial Functions and End Behavior

Learning Objective: 1.6.A

Describe end behaviors of polynomial functions.

Essential Knowledge: 1.6.A.1

As input values of a nonconstant polynomial function increase without bound, the output values will either increase or decrease without bound. The corresponding mathematical notation is lim⁡x→∞p(x)=∞\lim_{x \to \infty} p(x) = \infty or lim⁡x→∞p(x)=−∞\lim_{x \to \infty} p(x) = -\infty.

Essential Knowledge: 1.6.A.2

As input values of a nonconstant polynomial function decrease without bound, the output values will either increase or decrease without bound. The corresponding mathematical notation is lim⁡x→−∞p(x)=∞\lim_{x \to -\infty} p(x) = \infty or lim⁡x→−∞p(x)=−∞\lim_{x \to -\infty} p(x) = -\infty.

Essential Knowledge: 1.6.A.3

The degree and sign of the leading term of a polynomial determines the end behavior of the polynomial function, because as the input values increase or decrease without bound, the values of the leading term dominate the values of all lower-degree terms.
