Ex. {(1,3), (4,9),(8,9)} the domain is {1, 4, 8)
5
Range from a set
The set of all "outputs" or y-values
{(1,9)(-3,-5)(0,0)} the range is {9,-5,0}

Multiple Choice
For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.
D: {1, -3, -4,} R: {0, 1, 2, -4}
D: {-4, 0, 1, 2} R:{-4, -3, 1}
D: {0, 1, 2, 3, 4} R:{1, -3, -4}
D: {0, 1, 2, -4} R: {1, -3, -4, 1}
