To determine whether the data in the diagram is a function, we can use the definition of a function: each input (from the domain) must be paired with exactly one output (from the range).
- If an input corresponds to multiple outputs, it is not a function.
- If every input corresponds to one and only one output, it is a function.
Based on the options provided, if you are able to discern the pairs from the image, check if any x-values are repeated with different y-values.
Without the actual diagram to evaluate, I will assume based on the given options:
If:
- (a) No, it is not a function. The domain is the set {8, 7, 6, 5}. The range is the set {−1, 3, 2}.
- (b) No, it is not a function. The domain is the set {8, 7, 6, 5}. The range is the set {−1, 3, 2}.
- (c) Yes, it is a function. The domain is the set {−1, 3, 2}. The range is the set {8, 7, 6, 5}.
- (d) Yes, it is a function. The domain is the set {−1, 3, 2}. The range is the set {8, 7, 6, 5}.
- (e) Yes, it is a function. The domain is the set {8, 7, 6, 5}. The range is the set {−1, 3, 2}.
Please refer to your diagram to check if there are any repeating x-values with different y-values.
Once you establish if it is a function or not, you can select the appropriate option for the answer. If no repeating x-values are found, it's a function; if they are, it's not. The domain and range can be stated accordingly based on the input-output pairs visible in the image.
