Review: Domain & Range of Linear Functions

Front

What is the definition of the domain of 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 the range of 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

Back

The range is {9, 7, 5}.

Front

Back

The domain is discrete: D: {0, 1, 2, 3,...40}.

Front

Back

The range is R: {-240, -228, -216,..., 240}.

Front

What is the domain of the relation {(1,2), (3,4), (5,10)}?

Back

The domain is {1, 3, 5}.

Front

What is the range of the set of ordered pairs: (2, 11), (9, -3), (7, 21), (-8, 6)?

Back

The range is {-3, 6, 11, 21}.

Front

Back

The function is discrete.

Front

What is the difference between continuous and discrete functions?

Back

Continuous functions have an infinite number of possible values within a range, while discrete functions have specific, separate values.

Front

How do you find the range of a function given its domain?

Back

Substitute each value from the domain into the function to find the corresponding outputs, which form the range.
