dependent variable | a value or variable that depends upon the independent value |
function | a kind of relation in which one variable uniquely determines the value of another variable |
input | the independent variable of a function—input determines output |
linear function | a function with a constant rate of change and a straight line graph |
output | the dependent variable of a function—output is determined by input |
proportional function | a function in which the input times a constant equals the output |
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 |
