Front

What is the Range of a function?

Back

The set of all possible output values (y values) of a function.

Front

What does the notation y ≥ -4 represent?

Back

It indicates that the range of the function includes all values of y that are greater than or equal to -4.

Front

How do you find the domain of a function from a graph?

Back

Identify all the x values for which the function is defined.

Front

What is the domain of the graph represented by -3 ≤ x ≤ 4?

Back

The domain includes all x values from -3 to 4, inclusive.

Front

What is the range of a function?

Back

The set of all possible output values (y values) of a function.

Front

If a function has a domain of {-5, -2, 1, 4}, what does this mean?

Back

These are the only x values for which the function is defined.

Front

What does the notation -10 ≤ y ≤ 6 represent?

Back

It indicates that the range of the function includes all values of y from -10 to 6, inclusive.

Front

How can you determine if a function has all real numbers as its domain?

Back

If there are no restrictions on the x values, the domain is all real numbers.

Front

What is the significance of the domain in a function?

Back

The domain determines the possible inputs for the function.
