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

If y = 2x + 6, what is the output when the input is 2?

Back

10

Front

What are the domains for the graph: -6, 0, 2, 3, 4?

Back

The domains are the x-values: -6, 0, 2, 3, 4.

Front

What is the range of the relation with values (-8, -4, 4)?

Back

The range from least to greatest is (-8, -4, 4).

Front

Front

How do you determine if a relation is a function?

Back

A relation is a function if each input value corresponds to exactly one output value.

Front

What is an example of a function?

Back

An example is f(x) = x^2, where each x has one corresponding y.
