#y# represents exponential growth.

Explanation:

#y=2*(3)^x#

Here we have a constant #(2)# scaling a constant #(3)# raised to the power of positive #x#

Since the exponent is positive #x# determines that #y# represents exponential growth for increasing #x#

This can be seen by the graph of #y# below.
