,

(b) Point NOT in the Relation

• (1, 1)

• (4, 2)

• (-1, 1)

• (1, -1)

• (-2, 4)

Identify the domain of the relation

• D: { -7, -1, 0, 3}

• D: {-2, 0, 4 }

• D: { -2, -2, 0, 4 }

• D: { 0, 3, -1, -7, }

What do we make sure we do when writing the Domain and Range?

• in numerical order

• do not write repeated values

• make sure there is a y-value for every x-value

• make sure there is a x-value for every y-value

Is this a function?

• yes

• no
