Warm-up: Domain/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

How do you determine the domain of a graph?

Back

The domain is determined by identifying the x-values that the graph covers from left to right.

Front

How do you determine the range of a graph?

Back

The range is determined by identifying the y-values that the graph covers from bottom to top.

Front

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

Back

D: {1, 2, 3}.

Front

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

Back

R: {2, 3, 4}.

Front

What does it mean if a function has a domain of (-∞, ∞)?

Back

It means that the function is defined for all real numbers.

Front

What does it mean if a function has a range of [-1, 3]?

Back

It means that the output values of the function are between -1 and 3, inclusive.

Front

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

Back

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

Front

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

Back

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