Domain and Range - Cortez

Front

What is the definition of Domain in a relation?

Back

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

Front

What is the definition of Range in a relation?

Back

The range of a relation is the set of all possible output values (y-values) that result from the input values in the domain.

Identify the Domain in the relation: {(1, -4), (2, -1), (3, 2), (4, 5), (5, 0)}

Back

{1, 2, 3, 4, 5}

What is an example of a function?

Back

A function is a relation where each input (x-value) has exactly one output (y-value). For example, f(x) = x^2 is a function.

Front

What is the difference between Domain and Range?

Back

Domain refers to the set of input values, while Range refers to the set of output values in a relation.

How do you find the Domain of a function given its equation?

Back

To find the domain, identify all x-values that can be input into the function without causing any undefined situations (like division by zero or taking the square root of a negative number).
