Because your question only contains formulas without any other information on what x or lambda are, I'll give you a standard answer on how to plot:

You can use probability density functions:
y1=gampdf(x+1/lambda,2,1/lambda); y2=normpdf(x);

If X has a standard normal distribution, then (X^2)/2 has a gamma distribution with parameters lambda=1 and a=1/2.

Is the function f(x) a gamma function then? What’s the relationship between lamda and sigma?

What if I say lambda=1.1 and -5<=x<=5.
