# Functions

### Vocabulary for Algebra I - Functions

Continuous Graph p. 201 graphs made with a connected line or curve
Discrete Graph p. 201 graphs made with individual, distinct points
Relation p. 206 a set of ordered pairs
Domain p. 206 in a relation, the set of first coordinates (or x-values) of the ordered pairs
Range p. 206 in a relation, the set of second coordinates (or y-values) of the ordered pairs
Function p.207 a special type of relation that pairs each domain value with exactly one range value (the x-values cannot repeat)
Dependent Variable p. 216 In a function, the variable (usually "y") that you get by doing the calculation in the equation - it "depends" on what you plug into the equation for "x"
Independent Variable p. 216 In a function, the variable (usually "x") that is plugged into an equation to yield results for the dependent variable. Usually, you can pick any number for this value to create ordered pairs.
Function Notation p. 216 In a function, if "x" is independent and "y" is dependent, the function notation for "y" is "f(x)" - read "f of x". When you see function notation, it signals that the equation and resulting relation is a function.
Scatter Plot p. 224 a graph with points plotted to show a possible relationship between two sets of data.
Correlation p. 224 describes a relationship between two data sets
Positive Correlation p. 225 both sets of data values increase - scatter implies an upward sloping trend line
Negative Correlation p. 225 one set of data values increases as the other set decreases - scatter implies a downward sloping trend line
No Correlation p. 225 there is no relationship between the data sets - the scatter looks random
Trend Line p. 227 a line added to a scatter plot to help show the correlation between data sets more clearly
Sequence p. 234 a list of numbers that often form a pattern
Term p. 234 each number in a sequence
Arithmetic Sequence p. 234 when the terms in a sequence differ by the same amount - that is they are all the same distance apart
Common Difference p. 234 the distance "d" apart the numbers are in an arithmetic sequence

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.
