Domain and Range - Algebra 1 (Honors)

Front

What are all of the y values or outputs called?

Back

Range

Front

What is the range of the following graph? {-5, -1, 0 , 1, 5}, {-4, -2, 0, 3, 6}, (-4, 1) ( 6, 0), (6, 0)

Back

{-5, -1, 0 , 1, 5}

Front

What is the range? Remember range is the 'y' values (up and down) and an open circle means it DOES NOT equal that number - use < and >. Only use ≤ and ≥ with a closed circle.

Back

-3 < y < 3

Front

What is the DOMAIN of this graph? Remember: DOMAIN is the x from left to right.

Back

x > -3

Front

What is the domain? Remember domain is the 'x' values and an open circle means it DOES NOT equal that number - use < and >. Only use ≤ and ≥ with a closed circle.

Back

-4 ≤ x < 5

Front

Define 'Domain' in the context of functions.

Back

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

Front

Define 'Range' in the context of functions.

Back

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

Front

What does an open circle on a graph indicate?

Back

The value is not included in the domain or range.

Front

What does a closed circle on a graph indicate?

Back

The value is included in the domain or range.

Front

If a function has a domain of x ≥ 2, what does this mean?

Back

The function includes all x-values starting from 2 and going to infinity.
