Answer:
The graphed function is nonlinear.
Explanation:
When we talk about linear and nolinear funciton, we can distinguish them by using their graphs.
A linear function has a linear behaviour, that means it's representes by a straight line.
A nonlinear function doesn't have a straight line behaviour.
That's the easiest way to distinguish wether is a linear function or nonlinear.
Therefore, in this case, you can observe that the graph is not a straight line, that means the function is nonlinear.
