Front

What is a function?

Back

A function is a relation that assigns exactly one output (y-value) for each input (x-value).

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) for a function.

Front

Identify the independent variable in the relation: y = 3x + 2.

Back

The independent variable is x.

Front

Identify the dependent variable in the relation: y = 3x + 2.

Back

The dependent variable is y.

Front

What does it mean for a value to be in the domain of a function?

Back

A value is in the domain if it can be used as an input for the function without causing any mathematical errors.

Front

What does it mean for a value to be in the range of a function?

Back

A value is in the range if it can be produced as an output from the function.

Front

If the domain of a function is {1, 2, 3}, what are the possible x-values?

Back

The possible x-values are 1, 2, and 3.

Front

If the range of a function is {0, 1, 2}, what are the possible y-values?

Back

The possible y-values are 0, 1, and 2.

Front

What is an example of a function?

Back

An example of a function is f(x) = x^2, where each x-value has one corresponding y-value.
