Relations and Functions

Front

What is the plane containing the x-axis and the y-axis called?

Back

The coordinate plane.

Front

What is the point where the two axes intersect called?

Back

The origin.

Front

Is the relation a function? Why? (Example: x-value 11 has two y-values)

Back

No, because the x-value 11 has two y-values paired with it.

Front

What is the range of the graph R = { 2,3,-5,-3,-3,-5}?

Back

R = {-5, -3, 3}.

Front

What is the domain of the graph D = { 2,3,-5,-3,-3,-5}?

Back

D = {-5, -3, 2}.

Front

Define a function in terms of relations.

Back

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

Front

What are ordered pairs?

Back

Ordered pairs are pairs of numbers used to represent points on a coordinate plane, written as (x, y).

Front

What does the x-axis represent in a coordinate plane?

Back

The x-axis represents the horizontal line in a coordinate plane.

Front

What does the y-axis represent in a coordinate plane?

Back

The y-axis represents the vertical line in a coordinate plane.

Front

What is the difference between domain and range?

Back

Domain is the set of all possible input values (x-values), while range is the set of all possible output values (y-values).
