ALGEBRA I

4. function- simplest function that describes a family of functions
7. absolute deviation- average distance between each data point value and the mean
9. data- data for two different variables, usually related data
11. numbers- numbers that are not fractions/decimals and don’t repeat
13. data- when numbers are collected in their own categories
14. square trinomial- trinomial that can be factored into a binomial multiplied to itself
17. difference between the actual y-value and the predicted y-value
18. numbers- number that gives a negative result when squared
19. the measure of how spread out a set of data is
21. numbers- any number that can be expressed by a quotient or fraction

1. of best fit- straight line that runs through the middle of the data on a scatter plot
2. square root- positive square root of a number
3. of two squares- the subtraction of two perfect squares
4. defined function- function defined by two or more functions
5. formula- ax^2+bx+c
6. deviation- the measure of how spread out numbers are
8. numbers- all rational and irrational numbers
10. the function of a polynomial that gives you info on its roots
12. x-intercept of a quadratic function
15. amount of change in a ratio using the words “per” or “for every”
16. data- measurable data (numbers)
20. value- the distance between x and zero on the number line
