Algebra II EC

1. The set of all possible input values of x for a relation or function.
7. The shape of the graph of a quadratic function, has a symmetric u-shape.
11. Variation A relationship among three variables that can be written in the form y=kxz, where k is a nonzero function.
12. A number or product of numbers and variables and whole number exponents; a polynomial with only one term.
14. Common Denominator The least common multiple of two or more given denominators.
15. A measure of the strength and direction of the relationship between two variables or data sets.
16. The sum of all the values in a data set divided by the number of data values; also called the average.
18. A transformation that pushes the points of a graph horizontally toward the y axis or vertically toward the x-axis.
19. Can be found by solving adjacent divided by hypotenuse.
20. Point on a graph where a line crosses an axis.
21. A real number associated with a square matrix. Solved by multiplying across, then bottom minus top.

2. A member of the set of whole numbers and their opposites.
3. Can be found by solving hypotenuse divided by opposite
4. The side opposite the right angle in a right triangle.
5. System A system of equations containing only linear equations.
6. Binomials of the form a+b and a-b; the terms are the same; the signs before b are opposite.
8. A line that a graph approaches as the value of a variable becomes extremely large or small.
9. Point on the graph where the x and y axis meet.
10. Function A function whose graph is an unbroken line or curve with no gaps or breaks.
13. A possible result of a probability experiment.
14. of Best Fit The line that comes closest to all the points in a data set.
15. A number multiplied by a variable.
17. Fraction A fraction that contains one or more fractions in the numerator, the denominator, or both.
21. 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.
22. A rectangular array of numbers.
