Given: A graph of a function is given.
Required: To identify if the graph shows a function.
Explanation: A function is a relation between domain and range such that each value in the domain (x-values) corresponds to only one value in the range (y-values).
Also, we can not draw any vertical line that intersects the given graph at two different points.
Hence the given graph shows a function.
Final Answer: Option D is correct..
