The gaussian function p(x) = v2 73 is very important in probability and statistics. write a user-defined function (10 points) that takes as input the parameters x, u, and s and returns the value of the function evaluated for these parameters. you may use the numpy function numpy. exp() to calculate the exponential. then, write the programming commands (10 points) which call this function and plot it for x between -3 and 3 with u = 0 and s = 1 (for all values of x). be sure to label your axes and show the plot.
