- 2. of the graph of a linear inequality is a line in the coordinate plane. It separates the solutions of the inequality from the non solutions.
- 4. the possible
- 5. a positive angle measuring less than 90 degrees.You will use this term in geometry.
- 6. every number in an iternal with a single value. The graph of a __________can look like the step of a staircase
- 9. is the line that divides a figure into two parts that are mirror image. runs through the the middle of the parabola.
- 10. the sum of the data values divided by the number of data values is the mean.This is also called the average
- 12. when a number has two real roots, the positive root is called the _______. A radical sign indicates this.
- 15. a function is the input value for which the value of the function is zero. A____ of an equation is a value that makes the equation true.
- 16. the graph of a quadratic function. When you graph the line will make a u-shape
- 17. the is the distance between the center of the circle and any point on the circumference. This is half of the circumference.
- 18. is a quality whose value does not change. for example x+5=9, 5 and 9 are constants.
- 19. the minimum value of a function y=f(x) is the least y-value of the function. It is the y-coordinate of the lowest point on the graph.
- 20. are lines that intersect to form right angles. In the coordinate plane, _______ have slopes with product -1.
Down
- 1. the horizontal line through the average of the maximum and the minimum values. You can find this going right through the middle of you graph.
- 3. the____of a relation is the set of all inputs, or the ordered pairs.
- 7. two equation whose solutions are the same. These two equations will equal each other in the end.
- 8. is the middle value in a data set. If the data set contains an even number of values, the ___ is the mean of two middle values.
- 11. flips the graph of a function across a line, such as the x or y axis. Each point on the graph of the refelction as is the corresponding point on the graph of the original function.
- 12. are coplanar lines that do not intersect. These lines lay right across from each other. An example would be railroad tracks
- 13. is a transformation that turns a figure about a fixed point called the center of rotation. Will rotate either up or down.
- 14. is a values substantially different from the rest of the data set. For example is you have 56,64,73,59,98,65,59) the outlier would be 98.
