Exploring Relations and Functions in Algebra II

What is the domain in a relation?

• Set of output values

• Set of input values

• Set of equations

• Set of possible functions

In the context of functions, what is the range?

• The set of all possible outputs

• The graphical representation of the function

• The set of all possible inputs

• The formula used to map inputs to outputs

What is the significance of the domain in a function?

• It only includes negative numbers

• It is irrelevant to the function's definition

• It includes all possible equations

• It determines the scope of the function

What does it mean if a relation is also a function?

• Each input maps to multiple outputs

• Each input maps to exactly one output

• No inputs are required

• Outputs can have multiple inputs

What is an ordered pair in a relation?

• A function with two variables

• A type of mathematical equation

• A pair of numbers representing input and output

• A mapping of two functions

Can a function have the same output for different inputs?

• Yes, it's possible in functions

• Yes, but only in non-functions

• No, never

• Yes, always

Which scenario describes a non-function relation?

• All range elements map to at least one domain element

• A domain element maps to multiple range elements

• Some domain elements do not map to any range element

• Each domain element maps to a unique range element

How can you identify a function from a set of ordered pairs?

• Each input corresponds to multiple outputs

• No inputs correspond to outputs

• Each input corresponds to exactly one output

• Each output corresponds to one input

What happens if a domain element is associated with more than one range element?

• It can still be a function

• It is definitely a function

• It cannot be a function

• It is only a relation, not a function

What does it mean for a relation to be defined for a number in the domain?

• The number has at least one corresponding range element

• The relation does not involve numbers

• The number is excluded from the relation

• The number cannot have any corresponding range element
