What is the domain of a relation?

• the set of all x-values

• the set of all y-values

What is the domain?

• {0, 4, 10, 12}

• {1, 2, 4, 5, 10, 12}

• {1,2,5,2,5}

• {1, 2, 5}

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain from LEAST to GREATEST.

• D: {-4,-3,1}

• D:{0, 1, 2, -4}

• D:{-4,-3,0,1,2}

• D:{-4,0,1,2}
