Question

Determine whether the data in the diagram is a function, and state the domain and range.

domain range
4 1
3
2 4
1
(4 and 3 on domain go to 1 on range and 2 and 1 on domain go to 4 on range)
(1 point)
Responses

Yes, it is a function. The domain is the set {1, 4}. The range is the set {1, 2, 3, 4}
Yes, it is a function. The domain is the set {1, 4}. The range is the set {1, 2, 3, 4}

Yes, it is a function. The domain is the set {1, 2, 3, 4}. The range is the set { 1, 4}
Yes, it is a function. The domain is the set {1, 2, 3, 4}. The range is the set { 1, 4}

No, it is not a function. The domain is the set {1, 4}. The range is the set {1, 2, 3, 4}
No, it is not a function. The domain is the set {1, 4}. The range is the set {1, 2, 3, 4}

No, it is not a function. The domain is the set {1, 2, 3, 4}. The range is the set {1, 4}

Answer 1

Yes — it is a function. Every domain element (4, 3, 2, 1) maps to exactly one value.

Domain = {1, 2, 3, 4}
Range = {1, 4}
