Domain and Range Inequality Notation

Front

What is the Domain?

Back

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

Front

What is the Range?

Back

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

Front

What variable typically represents the range?

Back

y

Front

What does the notation -3 < x ≤ 3 mean?

Back

x is greater than -3 and less than or equal to 3.

Front

What does the notation -4 ≤ y ≤ 5 mean?

Back

y is greater than or equal to -4 and less than or equal to 5.

Front

Is the relation a function if an x-value has two y-values?

Back

No, because each x-value must have only one y-value.

Front

What is the Domain of the function f(x) = 2x + 3?

Back

All real numbers (x can be any value).

Front

What is the Range of the function f(x) = x^2?

Back

y ≥ 0 (y is greater than or equal to 0).

Front

How do you find the Domain of a function from a graph?

Back

Identify the x-values that the graph covers.

Front

How do you find the Range of a function from a graph?

Back

Identify the y-values that the graph covers.
