Domain and Range

Front

What is the domain?

Back

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

Front

What is the range?

Back

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

Front

All of the x values or inputs are called what?

Back

Domain

Front

What is the range of the function f(x) = x^2 for x in [-2, 2]?

Back

{0, 1, 4}

Front

What is the domain of the function f(x) = 1/x?

Back

All real numbers except x = 0.

Front

If the domain is {-4, -1, 0, 2, 7}, what are the possible outputs?

Back

The outputs depend on the function, but the range must be determined from the function's rule.

Front

What does it mean if a function is defined for all real numbers?

Back

It means the domain is (-∞, ∞).

Front

Find the RANGE of the function f(x) = 2x + 3 for x in {1, 2, 3}.

Back

{5, 7, 9}

Front

What is the domain of the graph represented by the inequality -4 ≤ x ≤ 2?

Back

{-4, -3, -2, -1, 0, 1, 2}

Front

If the range is {0, 4, 7}, what could be a possible domain?

Back

The domain could be any set of x-values that produce these y-values.
