Discrete vs. Continuous Graphs & Domain vs. Range

Front

What is a discrete graph?

Back

A discrete graph consists of distinct, separate points. It represents data that can only take specific values, often counted values.

Front

What is a continuous graph?

Back

A continuous graph represents data that can take any value within a given range. It is often used for measurements like time and distance.

Front

Give an example of a continuous variable.

Back

The time it takes for a light bulb to burn out.

Front

Give an example of a discrete variable.

Back

The number of students in a classroom.

Front

What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

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

Front

How do you determine the domain of a linear function?

Back

The domain of a linear function is usually all real numbers unless specified otherwise.

Front

How do you determine the range of a linear function?

Back

The range of a linear function can be determined by the slope and y-intercept, often expressed as y-values.

Front

What type of graph would represent the height of a plant over time?

Back

Continuous, because height can change gradually.

Front

What type of graph would represent the number of cars in a parking lot?

Back

Discrete, because the number of cars can only be whole numbers.
