- 4. A type of function that forms a parabola shape when graphed and is written as f(x)=ax^2+bx+c when put in standard form.
- 9. A type of number that can be represented as a fraction. These types of numbers include integers, perfect squares, natural numbers, repeating decimals, and terminating decimals.
- 10. A type of function that is written as f(x)=a^x.
- 17. A number between -1 and 1 that tells you the strength and direction of a relationship between variables.
- 18. The difference between the 3rd and 1st quartile of a data set.
- 19. The most common number that appears in the data set.
- 21. The middle point in a data set. The number in the middle of the data set when organized from least to greatest.
- 22. a symbol (typically a letter) used to represent a number or a mathematical object that is not known.
Down
- 1. the distance between a number and 0 on a number line. It is the value of a number not regarding its sign.
- 2. y2-y1/x2-x1 (hint: what formula is this?*include 'formula' in your answer)
- 3. A type of sequence of numbers where there is a constant rate of change. Each number is a the previous number plus a constant.
- 5. A type of number that cannot be represented as a fraction. These numbers are numbers that have decimals that continue forever but have no pattern (non-repeating and non-terminating). ex.:√2
- 6. An algebraic expression that consists of variables and coefficients.
- 7. A type of function that is a straight line when graphed. Has a constant rate of change and is written as y=mx+b when in slope-intercept form.
- 8. A measure of how dispersed the data is in relation to the mean. It is similar to MAD but squares the values and then takes the square root of it to get rid of the negatives.
- 11. A number in a data set that does not belong with the rest. An extreme number in a data set that is much larger or smaller than the rest of the data.
- 12. x=-b±√(b²-4ac)/2a
- 13. A formula used to find any number in a sequence.
- 14. A type of sequence of numbers in which each number is the previous number multiplied by a certain constant.
- 15. The average of a data set, found by adding all of the numbers and dividing that by how many numbers are in the data set.
- 16. A formula used to identify the next term in a sequence.
- 20. The difference between the largest number and smallest number in a data set.
