Is the graph a linear function nonlinear function or relation

C. Nonlinear function.

Step-by-step explanation:

We have been given a graph. We are asked to determine whether our given graph represents a linear function, nonlinear function or relation.

A. Relation.

Upon looking at our given graph, we can see our graph is continuous and it passes vertical line test, therefore, our given graph is a function and option A is not a correct choice.

B. Linear function.

The graph of our given function is not a straight line, therefore, our given graph is not a linear function.

C. Nonlinear function.

We can see that our given function is  symmetric about the origin, therefore our given function is an odd function or we can say that it is nonlinear function and option C is the correct choice.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
