HW 1.4

Front

What does f(x) represent in a function?

Back

f(x) is a different way to represent y.

Front

What is the definition of the range in a function?

Back

The set of all possible y-values.

Front

How do you find the domain of a function?

Back

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

Front

What is the definition of the domain in a function?

Back

The set of all possible x-values.

Front

What is the range of a function in inequality notation if it is 5 > y ≥ 1?

Back

The range includes all y-values from 1 to 5, including 1 but not including 5.

Front

What does the notation (-∞,-4)U(-4,4)U(4,∞) represent?

Back

It represents the domain of a function excluding the value -4 and 4.

Front

What is the significance of the domain in a function?

Back

The domain determines the input values for which the function is valid.

Front

How can you express the range of a function using interval notation?

Back

Use brackets and parentheses to indicate inclusive and exclusive endpoints.

Front

What is the relationship between domain and range in a function?

Back

The domain consists of input values (x-values), while the range consists of output values (y-values).

Front

What is an example of a function with a restricted domain?

Back

f(x) = 1/x has a restricted domain of all real numbers except x = 0.
