Retest - Week 3 (3rd Six Weeks) Module 2 - Topic 3

Front

What is a function?

Back

A function is a relation where each input (x-value) has exactly one output (y-value).

Front

What does it mean if a table has a repeated x-value?

Back

If a table has a repeated x-value, it means that the relation is not a function because one input corresponds to multiple outputs.

Front

How do you determine if a graph represents a function?

Back

A graph represents a function if any vertical line drawn through the graph intersects it at most once.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values).

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values).

Front

Given the function {(0,1), (1,-3), (2,-4), (-4,1)}, what is the domain?

Back

D: {0, 1, 2, -4}.

Front

Given the function {(0,1), (1,-3), (2,-4), (-4,1)}, what is the range?

Back

R: {1, -3, -4}.

Front

What is the difference between input and output in a function?

Back

Input refers to the x-values, while output refers to the y-values.

Front

What is a mapping in the context of functions?

Back

A mapping shows how each input is paired with an output.

Front

What does it mean if a mapping is not a function?

Back

A mapping is not a function if at least one input is paired with multiple outputs.
