Front

What is the definition of 'Domain' in a function?

Back

The set of all possible input values (x-values) for a function.

Front

What is the definition of 'Range' in a function?

Back

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

Front

Given the function f(x) = 2x + 3, what is the domain?

Back

The domain is all real numbers, as there are no restrictions on x.

Front

Given the function f(x) = 1/x, what is the domain?

Back

The domain is all real numbers except x = 0.

Front

What is the range of the function f(x) = x^2?

Back

The range is all real numbers greater than or equal to 0.

Front

How do you find the domain of a function from a set of ordered pairs?

Back

List all the first elements (x-values) from the ordered pairs.

How do you find the range of a function from a set of ordered pairs?

Back

List all the second elements (y-values) from the ordered pairs.

Front

For the function g(x) = x - 1, if the domain is {-1, 1, 2}, what is the range?

Back

The range is {-2, 0, 1}.

Front

What is the range of the function represented by the points (0, 0), (2, -4), (3, 3), (-2, 1)?

Back

The range is {-4, 0, 1, 3}.

Front

What is the domain of the function represented by the points (1, 2), (3, 4), (5, 6)?

Back

The domain is {1, 3, 5}.
