Plotting function with differenting constant

Hi,
I'm pretty unexperienced with Matlab so pls bear with me:
I'm trying to plot the function
y=a/(x+1)-(a-x)^2+x/(x+a)
when a is a vector of
a=[1,2,3,50,300]
so I put it in the loop:
for i=1:length(a)
ai=a(i);
y{i}=@(x) (ai/(x+1)-(ai-x)^2+x/(x+ai));
fplot(y{i});
end
but I get just one graph (of ai=300) and tons of yellow warnings..
any comments?

a=[1,2,3];%,50,300]; % using just the first 3 a values, for this demonstration
for i=1:length(a)
ai=a(i);
% y{i}=@(x) (ai/(x+1)-(ai-x)^2+x/(x+ai));
y{i}=@(x) (ai./(x+1)-(ai-x).^2+x./(x+ai)); % using element-wise operations (./ and .^) to vectorize
fplot(y{i});
hold on % using hold on to show multiple lines at once
end

Include the command
hold on
after the line
fplot(y{i});
such that preceeding graphs are not overwritten.
