ODE non homogeneous ploting graph

hello, everybody, is there any body who can help me to plot this equation in matlab.

y = -5e^2x+3e^x+3cosx+sinx

thanks.

I think the documentation of the plot function (here) will help a lot.

y = @(x) -5.*exp(2.*x) + 3.*exp(x) + 3.*cos(x) + sin(x);
fplot(y,[-20 1],'b-',"LineWidth",2)
