Front

What is the range of a function?

Back

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

Front

Given the function f(x) = x^2 + 2, what is the range when the domain is {-1, 0, 1}?

Back

The range is {2, 3}.

Front

What does it mean for a function to have a range of {10, 19, 26}?

Back

It means that the only output values the function can produce are 10, 19, and 26.

Front

How do you determine the range of a set of ordered pairs?

Back

The range is found by identifying all the second elements (y-values) in the ordered pairs.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) that the function can accept.

Front

Given the elements of f(x) as (-7, 3), (-1, 6), and (8, -3), what is the range?

Back

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

Front

What does the notation 2 < y ≤ 6 indicate about the range?

Back

It indicates that y can take any value greater than 2 and up to and including 6.

Front

If a function has a domain of {-5, -4, -3, -1}, what does this mean?

Back

It means that the function can only accept the input values -5, -4, -3, and -1.

Front

How can you find the range of a graphed function?

Back

By looking at the y-values of the points on the graph and identifying the minimum and maximum values.

Front

What is the significance of the range in real-world applications?

Back

The range can represent possible outcomes or values in real-world scenarios, such as profit, temperature, or speed.
