Name ____________________________________________ Date _____________ CHAPTER 3 VOCABULARY STUDY GUIDE – 8TH GRADE MATH A. Match the vocabulary terms with the correct definition. Write the answer in the blank. A. continuous graph B. coordinate plane C. dependent variable D. discrete graph E. domain F. function G. independent variable H. ordered pair J. origin K. quadrant L. range M. relation N. O. P. R. S. vertical line test x-axis x-coordinate y-axis y-coordinate ____ 1. A pair of numbers that can be used to locate a point on a coordinate plane ____ 2. The output of a function; a variable whose value depends on the value of the input, or independent variable ____ 3. A graph made up of unconnected points ____ 4. A test used to determine whether a relation is a function. If any vertical line crosses the graph of a relation more than once, the relation is not a function. ____ 5. The second number in an ordered pair; it tells the distance to move up or down from the origin ____ 6. The point where the x-axis and y-axis intersect on the coordinate plane ____ 7. A graph made up of connected lines or curves ____ 8. Each of the four regions into which the x- and y-axes divide the coordinate plane ____ 9. The horizontal axis on a coordinate plane ____ 10. The set of all possible input values of a function ____ 11. The first number in an ordered pair; it tells the distance to move right or left from the origin ____ 12. A set of ordered pairs ____ 13. Input of a function; a variable whose value determines the value of the output, or dependent variable ____ 14. The set of all possible output values of a function ____ 15. The vertical axis of a coordinate plane ____ 16. A plane formed by the intersection of a horizontal number line called the x-axis and a vertical number line called the y-axis ____ 17. An input-output relationship that has exactly one output for each input
