Question 2

An incomplete table of values for an exponential function is shown. The exponential function is of the form $$y=$$ $$a . b^{x}$$, where $$a$$ is a real number such that $$a 
eq 0$$ and $$b$$ is a positive real number not equal to 1 .

Complete the table with possible values for the exponential function and find the value of $$y$$ when $$x=3$$
