Function

A rule that matches each input or starting number to exactly one output or result.

Positive linear correlation

When one set of data goes up and the other set also goes up making a rising straight line pattern.

Negative linear correlation

When one set of data goes up but the other goes down making a falling straight line pattern.

Scatterplot

A graph that uses dots to show how two sets of data relate to each other.

f(x)

A way to show a function where x is the input and f(x) is the output or result

Trend line/line of best fit

A straight line drawn through data points on a scatterplot that best shows the overall pattern.

Inputs

The values you put into a function or rule.

Outputs

The values you get out of a function or rule after putting in the inputs.

Vertical line Test

A test on a graph where you draw vertical lines if any line touches the graph more than once, it is not a function.

Correlation/Trend

A pattern that shows how two things are related or move together.
