How to plot two functions in one graph?

I need to plot a graph where I can see how two functions interact with each other. Let's say first function is y1=a1*(x1^n)+b1*(x1^(n-1))+...+z1 and y2=a2*(x2^n)+b2*(x2^(n-1))+..+z2

Basically, y1 is a function of x1 and y2 is a function of x2.

I know that x1+x2=c, and I need to show where they intersect (if so) by showing them on the same graph, where y1 is starting from the left side and y2 is starting from the right side of the graph. The x axis' length should be equal to d.

Thanks.

Assuming that you have already evaluated ‘y1’ and ‘y2’ over the same (or similar) ranges of ‘x1’ and ‘x2’, the easiest way is to use the hold function:

figure(1)
plot(x1, y1)
hold on
plot(x2, y2)
hold off
grid

The grid call is optional but helpful.
