Which of the following graphs could represent a cubic function?

The graph that represents a cubic function is:

Graph A.

Step-by-step explanation:

We know that for the graph of a cubic function it satisfies the property that:

Graph B:

It is a graph of a linear function.

Since a graph of a linear function is a straight line.

Graph C:

It is a graph of a quadratic function.

Since both the ends of the graph are in the same direction.

Graph D:

It is also a graph of a linear function.

As the graph is a straight line.

Graph A:

It is a graph of a cubic function.

Since it satisfies all the above properties.

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)
