Solution:
C is the correct graph.
Step-by-step explanation:
We have been given the graph and we have to tell the type of the graph.
The graph of a quadratic function is a parabola. Hence, the given graph is not the graph of quadratic function.
A linear function represents a straight line. Hence, the given graph is not the graph of linear function.
The graph of a square root function looks like a half parabola. Hence, it must not be the graph of square root function.
The end behavior of a cubic function is "opposite at both ends". We can see that the given graph meets this criteria.
Hence, the given graph represents a cubic function.
C is the correct graph.
