Functions & Scatterplots Review

Front

What is a function?

Back

A function is a relation where each input (x-value) has exactly one output (y-value).

Front

How can you determine if a set of ordered pairs represents a function?

Back

Check if any x-value is repeated with a different y-value. If it is, it is not a function.

Front

What does a scatter plot show?

Back

A scatter plot displays the relationship between two variables using points on a Cartesian plane.

Front

What is a linear relationship in a scatter plot?

Back

A linear relationship is when the points form a straight line, indicating a constant rate of change.

Front

What is the vertical line test?

Back

If a vertical line intersects a graph at more than one point, the graph does not represent a function.

Front

What does it mean if a scatter plot has a positive correlation?

Back

As one variable increases, the other variable also increases.

Front

What does it mean if a scatter plot has a negative correlation?

Back

As one variable increases, the other variable decreases.

Front

What is the range of a function?

Back

The range is the set of all possible output values (y-values) of a function.

Front

What is the domain of a function?

Back

The domain is the set of all possible input values (x-values) of a function.

Front

How do you find the expected value from a scatter plot?

Back

Estimate the y-value corresponding to a given x-value based on the trend of the data points.
