Answer;

Step 1;

- Given gaussian function is; f(x) = .

Now , we have to sketch the graph the Gaussian for a = 0.5, 1, and 2.

If a = 0.5 , then the graph of the Gaussian function y= is;

If a = 1 , then the graph of the Gaussian function y= is ;

If a = 2 , then the graph of the Gaussian function y= is ;
