In this video, Mr. Becker explains the end behavior of polynomial functions by focusing on the degree and leading coefficient. He categorizes polynomials into odd and even degrees, showing how the end behavior differs based on these factors. For odd degree polynomials, the ends of the graph do opposite things, while for even degree polynomials, both ends behave the same. Examples are provided to illustrate these concepts using limit notation and graphing calculators.

What is the primary focus when analyzing the end behavior of a polynomial function?

• The number of terms in the polynomial

• The degree and leading coefficient

• The coefficients of all terms

• The constant term

For a polynomial function with an odd degree and a positive leading coefficient, what happens to the graph as x approaches positive infinity?

• The graph goes down

• The graph goes up

• The graph remains constant

• The graph oscillates

For a polynomial function with an odd degree and a negative leading coefficient, what happens to the graph as x approaches negative infinity?

• The graph oscillates

• The graph remains constant

• The graph goes down

• The graph goes up

What is a key characteristic of the end behavior of polynomial functions with odd degrees?

• The graph remains constant

• One end goes up and the other goes down

• Both ends of the graph go down

• Both ends of the graph go up

For a polynomial function with an even degree and a positive leading coefficient, what happens to the graph as x approaches positive infinity?

• The graph oscillates

• The graph remains constant

• The graph goes up

• The graph goes down

For a polynomial function with an even degree and a negative leading coefficient, what happens to the graph as x approaches negative infinity?

• The graph remains constant

• The graph goes up

• The graph goes down

• The graph oscillates

What is a key characteristic of the end behavior of polynomial functions with even degrees?

• One end goes up and the other goes down

• Both ends of the graph do the same thing

In the example f(x) = x^3 + 2x^2 - 11x - 12, what is the end behavior of the graph?

• Both ends go up

• Left end goes down, right end goes up

What is the leading coefficient in the polynomial function f(x) = x^3 + 2x^2 - 11x - 12?

• 2

• -11

• 1

• -12

In the example f(x) = 2x^2 - x - 3x^4, what is the end behavior of the graph?

• Left end goes up, right end goes down

• Left end goes down, right end goes up

• Both ends go down

• Both ends go up
