functions domain range

Front

What is the definition of the domain of a function?

Back

The domain of a function is the complete set of possible values of the independent variable (usually x) for which the function is defined.

Front

What is the definition of the range of a function?

Back

The range of a function is the complete set of possible values of the dependent variable (usually y) that result from using the function.

Front

Identify the domain of the relation: {(-6,14), (0,32), (2,38), (4,44)}.

Back

{-6, 0, 2, 4}

Front

What is the domain of the graph if y≥1?

Back

All real numbers.

Front

Is the mapping {(9,5), (10,5), (9,-5), (10,-5)} a function?

Back

Not a Function.

Front

What is the range of the function if the output is defined as y ≤ 6?

Back

Front

Which set of values represents a function? (3,4), (4,-3), (7,4), (3,8) or (6,-5), (7,-3), (8,-1), (9,1)?

Back

(6,-5), (7,-3), (8,-1), (9,1).

Front

What is a function?

Back

A function is a relation that assigns exactly one output (y) for each input (x).

Front

What is the vertical line test?

Back

The vertical line test is a method to determine if a curve is a graph of a function. If a vertical line intersects the graph at more than one point, it is not a function.

Front

What does it mean for a relation to be not a function?

Back

A relation is not a function if at least one input (x) is associated with more than one output (y).
