<ve number summary
The Tve number summary of a data set consists of the minimum, the three quartiles, and the maximum.
function
A function takes inputs from one set and assigns them to outputs from another set, assigning exactly one output to each input.
function notation
Function notation is a way of writing the outputs of a function that you have given a name to. If the function is named and is an input, then denotes the corresponding output.
graph of a function
The graph of a function is the set of all of its input-output pairs in the coordinate plane.
growth factor
In an exponential function, the output is multiplied by the same factor every time the input increases by one. The multiplier is called the growth factor.
growth rate
In an exponential function, the growth rate is the fraction or percentage of the output that gets added every time the input is increased by one. If the growth rate is 20% or 0.2, then the growth factor is 1.2.
increasing (function)
A function is increasing if its outputs get larger as the inputs get larger, resulting in an upward sloping graph as you move from left to right. A function can also be increasing just for a restricted range of inputs. For example the function given by is increasing for because the graph slopes upward to the left of the vertical axis.
intercept
A point on the graph of a function which is also on one of the axes.
inverse (function)
Two functions are inverses to each other if their input-output pairs are reversed, so that if one functions takes as input and gives as an output, then the other function takes as
