For f(x) = x + e^Bx^2 and B is a positive constant, Use MATLAB to produce graphs of f for B = 1, 5 , 10, 25, 50. All five plots should be shown together on the same axes, and the horizontal axis should represent the interval -2 <= x <= 2. Use MATLABs axis command to control the appearance of the plot. In your plot, also include a plot of a vector of zeros, so that the horizontal axis y = 0 is included.
