1.1 - Algebra 2 - Domain and Range from a Graph

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

True or False: The domain of a function can include negative numbers.

Back

True

Front

Express the interval (2, 5] in set notation.

Back

2 < x ≤ 5

Front

What is the domain of the function graphed if it includes all x-values from -3 to 4?

Back

-3 ≤ x ≤ 4

Front

Express the interval [-1, 3) in interval notation.

Back

[-1, 3) is already in interval notation.

Front

What does the notation '−∞ < x < ∞' represent?

Back

It represents that x can take any real number value.

Front

If a graph shows a function defined only for x-values from 1 to 6, what is the domain?

Back

1 ≤ x ≤ 6

Front

What is the range of a function if the lowest y-value is 0 and the highest is 10?

Back

0 ≤ y ≤ 10

Front

True or False: The range of a function can be all real numbers.

Back

True
