Functions
Across
- 1. The point at which a line intercepts the y-axis. Where x=0.
- 3. function whose graph is not connected by a line and is defined only for a set of numbers that can be listed, such as the set of whole numbers or the set of integers.
- 5. The value going into the function.
- 9. variable is a function of the independent variable.
- 10. The resulting value from the function.
- 12. When the rate of change varies from point to point.
- 15. Inputs are paired with outputs using (x,y) ordered pairs, tables, or mapping diagrams.
- 18. An equation whose solutions form a straight line on a coordinate plane.
- 24. A relationship between two quantities in which the ratio of one quantity to the other quantity is constant.
- 27. function whose graph is a connected line because the indendent variable can be any real number.
- 29. Slope-intercept form of a linear equation where the y-intercept is identified first.
Down
- 2. A slope that rises as the line is read from left to right.
- 4. variable that stands alone and is not dependent on another variable.
- 6. A ratio of the change in the independent variable to the corresponding change in the dependent variable.
- 7. rate A rate in which the second quantity in the comparison is one unit. Also known as slope.
- 8. A mathematical rule written using symbols.
- 11. A constant ratio of two variables related proportionally.
- 13. A ratio of the change in the y variable to the change in the x variable. Ideal when calculating slope when a graph is given.
- 14. pair A set of two numbers in which the order has an agreed up meaning.
- 16. The change in x-coordinates. Calculated as x2-x1.
- 17. A slope that does not remains flat as the line is read from left to right.
- 19. A relation that pairs each independent input from the domain with exactly one dependent output from the range.
- 20. equation of a linear function written as y=mx+b or y=b+mx.
- 21. The set of all independent/input (x) values in a relation.
- 22. A set of data that is made up of two paired variables.
- 23. The change in y-coordinates. Calculated as y2-y1.
- 25. A slope that falls as the line is read from left to right.
- 26. The set of all dependent/output (y) values in a relation.
- 28. Slope-intercept form of a linear equation where slope is identified first.
