M3 Lesson 1&2 (IF.1&2)

Front

What is the domain of a relation?

Back

The domain of a relation is the set of all possible input values (x-coordinates) for which the relation is defined.

Front

What is a function?

Back

A function is a relation in which each input (x-value) is associated with exactly one output (y-value).

Front

How can you determine if a relation is a function?

Back

A relation is a function if no x-value is repeated in the set of ordered pairs.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers (x, y) that represents a point in a coordinate system.

Front

Identify the domain of the relation {(0,−1),(2,−3),(3,−2)}.

Back

The domain is {0, 2, 3}.

Front

Which of the following represents a function? (0, 2), (1, 4), (2, 6), (1, 8)

Back

This does not represent a function because the x-value 1 is associated with two different y-values (4 and 8).

Front

Which set of ordered pairs represents a function? (-3, 4), (-2, 3), (-1, 2), (0, 4)

Back

This set represents a function because each x-value is unique.

Front

What is the range of a relation?

Back

The range of a relation is the set of all possible output values (y-coordinates) that correspond to the domain.

Front

What does it mean for y to be a function of x?

Back

It means that for each value of x, there is exactly one corresponding value of y.

Front

Identify the set where y is a function of x: {(1, 10), (1, 9), (1, 8), (1, 7)}

Back

This set does not represent a function because the x-value 1 is repeated with different y-values.
