Which description best describes the graph? linear increasing linear decreasing nonlinear increasing nonlinear decreasing

The description that best describes the given  graph is:

                 Nonlinear increasing.

From the graph that is provided to us we see that the value of x -variable increases the value of y-variable also increases.

i.e. the graph is a increasing graph.

Also, we know that the graph of a linear function is a straight line.

But here the curve of the graph does not seem to be a straight line.

             Hence, the graph is:

              Non linear increasing.
