I'm facing problem to write a function in which more than 2 variables are varying from one fixed value to another. How to write a function for it?

How to write a function in which more than 2 variables are varying from one fixed value to another. e.g. Y= a*x^2 + b*x + c;

a = 1: 2: 10

b = 1: 1: 20

c = 5: 3: 15

x = 2: 4: 25

How about a bunch of plots where c varies in each plot (lots of curves for different c in each plot), and you get a different plot for each a, b pairing:

a = 1: 2: 10
b = 1: 1: 20
c = 5: 3: 15
x = 2: 4: 25
rows = ceil(sqrt(length(a) * length(b)))
loopCounter = 1;
for k1 = 1 : length(a)
	thisa = a(k1);
	fprintf('a(%d) = %d\n', k1, thisa);
	for k2 = 1 : length(b)
		thisb = b(k2);
		for k3 = 1 : length(c)
			thisc = c(k3);
			subplot(rows, rows, loopCounter);
			Y = thisa * x .^ 2 + thisb .* x + thisc;
			plot(x, Y, '-', 'LineWidth', 2);
			hold on;
			caption = sprintf('a(%d) = %d.   b(%d) = %d\n', k1, thisa, k2, thisb);
			title(caption);
		end
		loopCounter = loopCounter + 1;
		drawnow;
	end
end

Thank you so much, by changing some modifications in this program i am getting my results.
