Plotting dot to denote a a specific point in a curve

Hello,
I was wondering how to plot a dot specifying a point along a curve that I'm plotting.
My code is the following:
x=-20:0.01:20;
y=x.^5-4*x.^4+3*x.^2+8;
y0=ones(1,length(x))*15;
hold on;
zoom xon; zoom yon;
zoom on;
plot(x,y);
plot(x,y0, '--g', 'LineWidth',2),axis([-2 4,-80, 60]);
I want to plot on the intersection between the two plots. I know where it is located (using the zoom function allows me to easily find it) but I don't know the specific syntax required to put a dot there.
Any feedback would be greatly appreciated.

Just use plot as you have done before using scalar inputs for the x and y coordinates rather than the vectors used previously.
