Finding Domain and Range

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (independent variables) for which the function is defined.

Front

What is the range of a function?

Back

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

Front

True or False: The domain of a function is the same as the set of dependent variables.

Back

False

Front

True or False: The range of a function is the same as the set of independent variables.

Back

False

Front

What is a dependent variable?

Back

A dependent variable is a variable whose value depends on the value of another variable.

Front

What is an independent variable?

Back

An independent variable is a variable that is manipulated or changed in an experiment to observe its effect on a dependent variable.

Front

In the equation y = 2x + 3, what is the independent variable?

Back

The independent variable is x.

Front

In the equation y = 2x + 3, what is the dependent variable?

Back

The dependent variable is y.

Front

If a function has a domain of {1, 2, 3}, what are the possible input values?

Back

The possible input values are 1, 2, and 3.

Front

If a function has a range of {4, 5, 6}, what are the possible output values?

Back

The possible output values are 4, 5, and 6.
