Discrete Domain and Range

Front

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

Back

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

Front

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

Back

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

Front

Given the function {(0,1), (1,-3), (2,-4), (-4,1)}, what is the domain?

Back

D: {-4, 0, 1, 2}.

Front

Given the function {(0,1), (1,-3), (2,-4), (-4,1)}, what is the range?

Back

R: {-4, -3, 1}.

Front

True or False: The coordinates of a point are represented as (x, y).

Back

True.

Front

What is the domain of the function represented by the ordered pairs {(1, 2), (2, 3), (3, 4)}?

Back

D: {1, 2, 3}.

Front

What is the range of the function represented by the ordered pairs {(1, 2), (2, 3), (3, 4)}?

Back

R: {2, 3, 4}.

Front

If a function has the ordered pairs {(1, 5), (2, 5), (3, 6)}, what is the range?

Back

R: {5, 6}.

Front

What does it mean if a function is not defined for certain x-values?

Back

It means those x-values are not included in the domain of the function.

Front

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

Back

List all the unique x-values from the ordered pairs.
