# Polynomial Graphs

### Vocabulary related to graphs of polynomial functions

TermDefinition
Turning Points Where the graph changes direction
Degree of Polynomial The highest exponent in the polynomial
Leading Coefficient The number in front of the variable in the term with the highest exponent
y-Intercept The point where the graph crosses the y-axis
Global Max/Min The absolute highest or lowest point on a graph
Local Max/Min High and Low points that occur at turning points; Not necessarily the absolute highest and lowest point on a graph
Zeros The x-value that makes the function equal 0; a real zero is an x-intercept of the graph
Multiplicity The number of times a particular number is a zero of a polynomial
What happens on the graph at a zero with an even multiplicity? The graph bounces on the x-axis
What happens on the graph at a zero with an odd multiplicity? The graph crosses the x-axis
End behavior of an odd degree polynomial with a positive leading coefficient Falls left, rises right
End behavior of an odd degree polynomial with a negative leading coefficient Rises left, falls right
End behavior of an even degree polynomial with a positive leading coefficient Rises left, rises right
End behavior of an even degree polynomial with a negative leading coefficient Falls left, falls right
The number of zeros of a polynomial The number of zeros is equal to the degree of the polynomial

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
