Exploring Polynomials and Their End Behavior

This video tutorial covers the basics of polynomials, including their components such as terms, coefficients, and exponents. It explains how to identify polynomial functions, write and multiply polynomial equations, and understand the end behavior of polynomial graphs. The tutorial also demonstrates how to graph polynomial functions, identify key features, and factor polynomials to find zeros.

What does the term 'polynomial' mean?

• Many terms

• A single term

• A decimal

• A fraction

Which of the following is a requirement for the exponents in a polynomial?

• They must be decimals

• They must be non-negative integers

• They must be negative integers

• They must be fractions

Why can't a polynomial function have an exponent that is a fraction?

• Because it would make the polynomial undefined

• Because the exponents must be non-negative integers

• Because fractions are not allowed in mathematics

• Because fractions are not real numbers

What is the leading coefficient in a polynomial equation?

• The sum of all coefficients

• The highest exponent

• The constant term

• The coefficient of the term with the highest exponent

What happens to the ends of a polynomial function with an even degree and a positive leading coefficient?

• They go up and down

• They go down and up

• They both go up

• They both go down

How do you describe the end behavior of a polynomial function?

• By checking the number of terms

• By examining the constant term

• By considering the leading coefficient and the highest degree

• By looking at the middle terms

Which of the following is NOT a characteristic of a polynomial graph?

• Smooth and continuous

• Curvy

• Having sharp bends

• Having gaps or holes

What is the y-intercept of a polynomial function?

• The lowest point on the graph

• The point where the graph crosses the y-axis

• The point where the graph crosses the x-axis

• The highest point on the graph

How do you find the zeros of a polynomial function?

• By looking at the constant term

• By examining the leading coefficient

• By finding the highest exponent

• By setting the polynomial equal to zero and solving for x

What is the degree of a polynomial function?

• The constant term

• The sum of all coefficients

• The highest exponent of the variable

• The number of terms in the polynomial
