Answer:
Option (3).
Step-by-step explanation:
Attached figure is the graph of a function,
f(x) = -
Since domain of any function is the set of all possible input values of the function,
Therefore, Domain of the function is,
Domain : x ≤ 0 Or (-∞, 0]
And range of the function is the set of all possible output values (y-values) of the function.
Therefore, Range of the function will be,
Range : y ≤ 0 Or (-∞, 0]
Therefore, Domain and range of this function is same.
Option (3) will be the answer.
Answer:
- Node G has the highest degree (6), hence is the most central. Node B has the second highest degree (5), so is one of the most central. (You have also added nodes with degrees 4 and 3. I might not.)
- Node F has the same structure as Node D. (Your answer agrees.)
- See the right-most column of the attachment.
Step-by-step explanation:
1. Only one "actor" (G) has the highest degree, 6. That corresponds to selection E. Whether you include other actors in your list of "most central" depends on your interpretation of that term. My interpretation is that only the node with highest degree is of interest here.
2. Node that are structurally equivalent are ones with the same set of neighbors. Nodes D and F both have E and G as neighbors, so are structurally equivalent. Selection A is appropriate.
3. The problem seems to be to list the neighbors and add their degrees for any given actor. The attachment does that. The measure C(x) is listed in the rightmost column for each actor x listed in the leftmost column.
