Vocabulary for mid-term chapter 5
| Question | Answer |
|---|---|
| Axes | Two perpendicular number lines that are used to locate points on a coordinate plane |
| Complete graph | Show the origin, the points at which the graph crosses the x-axis and y axis and other important characteristics of the graph |
| Completeness property for points in the plane | exactly one point in the plane is named b a given ordered pair of numbers |
| Coordinate plane | the plane containing the x and y axes |
| Domain | the set of all first coordinates from the ordered pairs in a relation |
| Equation in two variables | an equation that contains two unknowns |
| Function | a relation in which each element of the domain is paried with exactly one element of the range |
| Function notation | The equation y=x+5 written as f(x) = x+5 |
| Graph | to draw, or plot, the points named by certain numbers or ordered pairs on a number line or coordinate plante |
| Interquartile range | the difference between the upper and the lower quartile in a set of data |
| inverse of a relation | obtained by switching the coordinates in each ordered pair |
| linear equation | an equation whose graph is a straight line |
| linear equation in standard form | can be written in the form Ax + By = C |
| linear function | an equation whose graph is a nonvertical line |
| lower quartile | divides the lower half of a set of data into two equal parts |
| mapping | pairs one element in the domain with one element in the range |
| origin | the point of intersection of the two axes in the coordinate plane |
| outlier | a value that is much greater or much less than the rest of the data in a set of data |
| quadrants | one of the four regions into which teh x- and y-axes separate the coordiante plane |
| quartiles | values that divide the date into four equal parts |
| range (when dealing with a relation) | the set of all second coordinates from the ordered pairs in the realation |
| relation | a set of ordered pairs |
| solution of an equation in two variables | if a true statement results when the nubmers in an ordered pair are substituted into an equation |
| upper quartile | divides the upper half of a set of data into two equal parts |
| verticle line test | if any verticle line passes through no more than 1 point of the graph of a relation, the relation is a function |
| x-axis | the horizontal number line |
| x-coordinate | the first number in an ordered pair |
| y-axis | the verticle number line |
| y -coordiante | the second number in an ordered pair |
| use a table | a problem-solving strategy that uses tables to organize and problem solve |
