Front

What is the domain in a mathematical function?

Back

The domain is the set of all possible input values (x-values) for which the function is defined.

Front

What does it mean if a function has a domain of -2 to 2?

Back

It means that the function accepts input values ranging from -2 to 2, inclusive.

Front

What are the possible outputs of a function with a domain of -2 to 2?

Back

The outputs can vary depending on the function, but for the given domain, the outputs must be calculated based on the function's rule.

Front

How do you express multiple answers in a list format?

Back

You separate the answers with a comma and a space, e.g., 1, 2, 3.

Front

What is an example of a function that has a domain of -2 to 2?

Back

An example is f(x) = x^2, where x can take any value from -2 to 2.

Front

What is the range of a function?

Back

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

Front

If a function has outputs of -2, -7, 2, and 5, what can we say about its range?

Back

The range includes the values -7, -2, 2, and 5.

Front

What is the importance of defining the domain and range of a function?

Back

Defining the domain and range helps to understand the behavior of the function and the values it can take.

Front

What does it mean to type answers separated by a comma and a space?

Back

It means to list the answers in a single line, ensuring clarity and proper formatting.

Front

How can you find the outputs of a function for a given domain?

Back

You substitute the input values from the domain into the function's equation.
