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).

  1. If an input corresponds to multiple outputs, it is not a function.
  2. 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.

Based on the information you provided:

  • 8 points to 2
  • 7 points to 3
  • 6 points to 2
  • 5 points to 2

Function Evaluation:

To determine if this set of points represents a function, we need to check if each input (domain) has only one corresponding output (range):

  • The input 8 corresponds to the output 2 (one output).
  • The input 7 corresponds to the output 3 (one output).
  • The input 6 corresponds to the output 2 (one output).
  • The input 5 corresponds to the output 2 (one output).

Here, although the input 2 appears multiple times as an output for multiple inputs (6 and 5), this does not violate the rule of a function, as each input is still paired with only one output.

Conclusion:

The provided data is a function because every input corresponds to exactly one output.

Domain and Range:

  • Domain: {8, 7, 6, 5}
  • Range: {-1, 3, 2}

Based on this conclusion, the correct response from the options would be:

Yes, it is a function. The domain is the set {8, 7, 6, 5}. The range is the set {−1, 3, 2}.
