Across 2. Another name for trend line. Normally written as an equation of the line. 5. a graph relating two sets of data with no actual values. A sketch of a series of events. 8. The set of all input values (x) in a relation. 9. A trend where both sets of data increase together. Graph moves upward. 10. Functions written in the form f(x) = 12. A trend where one set of data increases in value as the other set decreases. Graph moves downward. 14. A variable whose value relies on the value of a second variable. It changes based on the other variable. Output. 16. A graph that relates two sets of data graphed as ordered pairs 23. A trend between two sets of data 24. A test used to determine if a graph is a function vs. relation. 25. A word used to describe data that is measured and can be used to make predictions 26. A U shaped graph. 27. A relationship between two sets of data 28. A function whose graph makes a parabola. 29. A line that can be drawn through a scatterplot to show the correlation 30. A variable that can take on any value. Does not rely on other variables for its value. Input.

Down 1. A function whose graph makes a V shape up or down. 3. A model that can be used to understand and describe functions. 4. A member or item of a set. 6. A word used to describe data that is counted. Cannot necessarily make predictions between data points. 7. A function whose graph forms a straight line. 11. The pair of numbers (x, y) that give the location of a point on a coordinate plane. 13. A group of numbers, variables, objects that are written using braces {}. 15. The set of all output values (y) in a relation. 17. Two sets of data that are not dependent on each other. 18. A function whose graph does not form a straight line. 19. A word used to describe two sets of different data. 20. A special type of relation where each input value has exactly one specific output value. It follows a rule. 21. An equation that describes a function. 22. A set whose elements are all ordered pairs.
