If a set of ordered pairs represents a function, what should be true about the pairs?

• Each input has multiple outputs

• Inputs and outputs are not related

• Each input has exactly one output

• Each output has multiple inputs

What is the purpose of determining the domain and range of a function?

• To find the average of the function

• To determine if the function is continuous

• To create a graph of the function

• To understand the set of possible inputs and outputs of the function

What is the range of a function?

• The set of all possible outputs

• The set of all possible inputs

• The set of all possible relations

• The set of all possible functions

In a function represented by a set of ordered pairs, what does it mean if two different inputs have the same output?

• The function is quadratic

• The function is linear

• The relation is a function

• The relation is not a function

In a graph of discrete points representing a function, what does each point typically represent?

• Unrelated values

• Multiple inputs for a single output

• Multiple outputs for a single input

• An ordered pair of input and output values

How can you determine if a relation is a function when given a table of values?

• Check if inputs and outputs are not related

• Check if each input has multiple outputs

• Check if each output has multiple inputs

• Check if each input has exactly one output

If a function is represented by a table, what does it mean if there are repeated input values with different output values?

• The function is quadratic

• The relation is not a function

• The function is linear

• The relation is a function

If a function is represented by a graph, what does the y-axis typically represent?

• Input values

• Unrelated values

• Output values

• Both input and output values

If a function is represented by a table, what does each row in the table typically represent?
