1. The set of numbers {1,2,3,...} are called the ___ numbers. natural
2. The set of numbers {..., -3,-2,-1,0,1,2,3,...} are called the ___ . integers
3. The set of numbers that can be expressed as a ratio of two integers are the ___ numbers. rational
4. When they are in their decimal form, rational numbers will be ___ or ___ decimals. terminating, repeating
5. When they are in their decimal form, irrational numbers will be ___ and ___ decimals. nonterminating, nonrepeating
6. The set containing both rational and irrational numbers are the ___ numbers. real
7. A number is in scientific notation if it is in the form c x 10^n where the condition on c is that ___ and n is a/an ____. the absolute value of c is greater than or equal to 1 and less than 10, n is an integer
8. If you take a number whose absolute value is less than one, and rewrite it in scientific notation c x 10^n, the exponent n will be ___. negative
9. If you take a number whose absolute value is greater than ten, and rewrite it in scientific notation c x 10^n, the exponent n will be ___. positive
10. If you have a number in exponential notation, k x 10^m, where |k|<1, and rewrite it in scientific notation, c x 10^n, the new exponent n will be ___ than the old exponent m. smaller
11. If you have a number in exponential notation, k x 10^m, where |k|>10, and rewrite it in scientific notation, c x 10^n, the new exponent n will be ___ than the old exponent m. bigger
12. The name we use for a set of ordered pairs is a ___. relation
13. We often use the notation (x,y) to name a set of ordered pairs. The set containing all of the x's is called the ___. domain
14. We often use the notation (x,y) to name a set of ordered pairs. The set containing all of the y's is called the ___. range
15. A relation between two sets so that each member of the first set goes with exactly one member of the second set is called a ___. function
16. A function is a ___ between ___ ____ so that each member of the ___ corresponds to ___ ___ member of the ___. relation, two sets, domain, exactly one, range
17. We can determine whether a graph is that of a function by applying the Vertical Line Test. The graph is that of a function if ___. every vertical line crosses the graph at most once
18. The easiest way to show that a relation is not a function is to find one member of the ___ that goes with two members of the ___. domain, range
19. For a function f, f(a)=b means the point __ is a point on the graph. (a,b)
20. For a function f, if the point (a,b) is a point on the graph, then f(__)=___. a,b
21. If f(a)=b, then the function sends the x-value ___ to the y-value ___. a, b
22. We read the symbols "f(x)" as___. f of x
23. If you are given the graph of f, and are asked to find f(a) for some number a, you find the point on the graph where the ___-value is a, then find the ___-value of that point. The answer to f(a) is that ___-value. x,y,y
24. If you are given the graph of f, and are asked to solve f(x)=b for some number b, you find the point(s) on the graph where the ___-value is b, then find the ___-value of that/those point(s). The answer to f(x)=b is that/those ___-value(s). y,x,x
25. For a function f, the formula to find the average rate of change of f from a to b is ___. (f(b)-f(a))/(b-a)
26. For a function f, the formula to find the average rate of change of f as x increases from x1 to x2 is ___. (f(x2)-f(x1))/(x2-x1)
27. Suppose that the graph of f contains the points (x1, y1) and (x2, y2). Then, the average rate of change of f as x increases from x1 to x2 is ___. (y2 - y1)/(x2 - x1)
28. The slope of the line containing the points (x1, y1) and (x2, y2) is ___. (y2 - y1)/(x2 - x1)
29. If f is a linear function, then the slope of the function between x1 and x2 is ___. (f(x2)-f(x1))/(x2-x1)
30. If a function can be written in the form f(x)=ax+b, where a and b are numbers, it is called a ___ function. linear
31. For a linear function f(x)=ax+b, a is the ___ and b is the __. slope, y-intercept
32. The point where a graph crosses the y-axis is called the ___ of the graph. y-intercept
33. We say a graph is increasing on the interval a < x < b if, as you move along the graph from left to right, between x=a and x=b, the y-values get ___. bigger
34. We say a graph is decreasing on the interval a < x < b if, as you move along the graph from left to right, between x=a and x=b, the y-values get ___. smaller
35. What is the interval notation for the set of x's that are greater than a and less than b? (a,b)
36. What is the interval notation for the set of x's that are greater than or equal to a and less than or equal to b? [a,b]

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.
