Extra Credit for Unit 1 Vocab
| Question | Answer |
|---|---|
| Arithmetic Sequence | a sequence whose successive terms differ by the same nonzero number d, called the common difference (adding the same term each time) |
| Constant of Proportionality | the constant k in direct and inverse variation equations |
| Continuous | a function whose graph is an unbroken line or curve with no gaps or breaks |
| Discrete | a function whose graph is made up of unconnected points |
| Domain | the set of all first coordinates (or x-values) of a relation or function |
| Function | a relation in which every domain value is paired with exactly one range value (every input has exactly one output) |
| Function Notation | If x is the independent variable and y is the dependent variable, then the function notation for y is f (x), read “f of x,” where f names the function. |
| Initial Value | the starting value or the y-intercept of a graph, b |
| Interval Notation | a way of writing subsets of the real number line using endpoints, parentheses(), and/or brackets[] |
| Linear Function | A function that can be written in the form y = mx + b, where x is the independent variable and m and b are real numbers. Its graph is a line. |
| Parent Function | The simplest function with the defining characteristics of the family. Functions in the same family are transformations of their parent function |
| Point-Slope Form | the equation of a line in the form of y - y1 = m(x - x1), where m is the slope and (x,y) is a specific point on the line |
| Proportional Relationships | relationships between two equal ratios |
| Range | the set of all second coordinates (or y-values) of a function or relation |
| Rate of Change | a ratio that compares the amount of change in a dependent variable to the amount of change in an independent variable |
| Slope | a measure of the steepness of a line, calculated by dividing the rise by the run of a graph |
| Slope-intercept form | a linear equation written in the form y = mx + b, where m represents slope and b represents the y-intercept |
| Standard form | a linear equation written in the form Ax + By = C, where A, B and C are real numbers and A and B are not both 0 |
| x-Intercept | The x-coordinate of the point where a graph intersects the x-axis. |
| y-Intercept | The y-coordinate of the point where a graph intersects the y-axis. |
