4.3 Discrete vs. Continuous and One-to One Practice

Front

What is discrete data?

Back

Discrete data consists of distinct or separate values. It can be counted and often involves whole numbers, such as the number of students in a class.

Front

What is continuous data?

Back

Continuous data can take any value within a given range. It is measurable and can include fractions or decimals, such as height or temperature.

Front

Give an example of discrete data.

Back

The number of suitcases lost by airlines is an example of discrete data.

Front

Give an example of continuous data.

Back

The temperature at noon is an example of continuous data.

Front

What is a one-to-one function?

Back

A one-to-one function is a function where each input has a unique output, meaning no two different inputs produce the same output.

Front

What is a function?

Back

A function is a relation that assigns exactly one output for each input.

Front

Is the relation in the graph a function if it passes the vertical line test?

Back

Yes, if a graph passes the vertical line test, it is a function.

Front

What does it mean if a function is not one-to-one?

Back

If a function is not one-to-one, it means that at least two different inputs produce the same output.

Front

What is the vertical line test?

Back

The vertical line test is a method to determine if a curve is a function by checking if any vertical line intersects the curve at more than one point.

Front

Can continuous data be represented on a graph?

Back

Yes, continuous data can be represented on a graph with a smooth line or curve.
