Domain and Range Discrete

Front

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

Back

The domain of a function is the complete set of possible values of the independent variable (input) for which the function is defined.

Front

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

Back

The range of a function is the complete set of possible values of the dependent variable (output) that results from the function.

Front

Identify the domain of the relation given by the pairs (2,3), (4,5), (6,7).

Back

The domain is {2, 4, 6}.

Front

Identify the range of the relation given by the pairs (2,3), (4,5), (6,7).

Back

The range is {3, 5, 7}.

Front

What does it mean for data to be 'discrete'?

Back

Discrete data consists of distinct or separate values, often counted in whole numbers.

Front

What does it mean for data to be 'continuous'?

Back

Continuous data can take any value within a given range and is often measured.

Front

Given the mapping {(-2, 1), (0, 3), (1, 5)}, what is the domain?

Back

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

Front

Given the mapping {(-2, 1), (0, 3), (1, 5)}, what is the range?

Back

The range is {1, 3, 5}.

Front

What is the domain of the function f(x) = 1/x?

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 y such that y >= 0.
