| constant of proportionality | the constant in a proportional function equation; it describes the ratio or proportional relationship of the independent and dependent variables—also called the constant of variation or the rate of change |
| constant of variation | the constant in a proportional function equation; it describes the ratio or proportional relationship of the independent and dependent variables—also called the rate of change or the constant of proportionality |
| continuous pattern | a pattern made of uninterrupted or connected values or objects |
| dependent value | a value or variable that depends upon the independent value |
| dependent variable | a value or variable that depends upon the independent value |
| discrete pattern | a pattern made of separate and distinct values or objects |
| discrete values | values that change in increments (not continuously) |
| domain | the set of all possible inputs of a function which allow the function to work |
| exponential function | a nonlinear function in which the independent value is an exponent in the function, as in y = abx |
| function | a kind of relation in which one variable uniquely determines the value of another variable |
| independent value | a value or variable that changes or can be manipulated by circumstances |
| independent variable | a value or variable that changes or can be manipulated by circumstances |
| inductive reasoning | a form of logical thinking that makes general conclusions based on specific situations, inductive reasoning takes the path of observation to generalization to conjecture |
| input | the independent variable of a function—input determines output |
| inverse function | a nonlinear function in which the reciprocal of the independent variable times a constant equals the dependent variable, as in |
| linear function | a function with a constant rate of change and a straight line graph |
| mathematical sequence | an ordered list of numbers or objects |
| nonlinear function | a function with a variable rate of change that graphs as a curved line |
| output | the dependent variable of a function—output is determined by input |
| parabola | a U-shaped graph which is produced by a quadratic equation |
| proportional function | a function in which the input times a constant equals the output |
| quadratic function | a function of the form y = ax2 + bx + c where a is not equal to zero |
| range | the set of all possible outputs of a function |
| rate of change | the constant in a proportional function equation; it describes the ratio or proportional relationship of the independent and dependent variables—also called the constant of variation or the constant of proportionality |
| relation | the relationship between variables that change together |
| term | a value in a sequence--the first value in a sequence is the 1st term, the second value is the 2nd term, and so on; a term is also any of the monomials that make up a polynomial |
