\

To determine whether the given function is linear o, exponential, or neither.

\

First compute the average rate of change of \"\" with respect to \"\" and then compute the ratio of the consecutive outputs.

\

If the average rate of change is constant, then the function is linear else non-linear.

\

Observe the above table, for the given function, the average rate of change from \"\" to \"\" is \"\", and from   \"\" to \"\" is \"\".

\

Since the average rate of change is not constant , the function is a non- linear function.

\

\"\"

\

The function is  non-linear  and tno slope.
