3. The set of all possible input values of x for a relation or function.
4. Variation A linear relationship between two variables, x and y, that can be written in the form "y=kx" where k is a nonzero constant.
6. A measure of the strength and direction of the relationship between two variables or data sets.
8. The shape of the graph of a quadratic function, has a symmetric u-shape.
11. A real number associated with a square matrix. Solved by multiplying across, then bottom minus top.
13. Can be found by solving hypotenuse divided by opposite
14. A transformation that pushes the points of a graph horizontally toward the y axis or vertically toward the x-axis.
16. Point on the graph where the x and y axis meet.
17. A possible result of a probability experiment.
20. A number or product of numbers and variables and whole number exponents; a polynomial with only one term.
22. of Best Fit The line that comes closest to all the points in a data set.
23. The sum of all the values in a data set divided by the number of data values; also called the average.

1. Can be found by solving adjacent divided by hypotenuse.
2. A member of the set of whole numbers and their opposites.
5. Point on a graph where a line crosses an axis.
6. A number multiplied by a variable.
7. The side opposite the right angle in a right triangle.
9. Common Denominator The least common multiple of two or more given denominators.
10. Binomials of the form a+b and a-b; the terms are the same; the signs before b are opposite.
12. A line that a graph approaches as the value of a variable becomes extremely large or small.
14. Function A function whose graph is an unbroken line or curve with no gaps or breaks.
15. Variation A relationship among three variables that can be written in the form y=kxz, where k is a nonzero function.
18. A rectangular array of numbers.
