Hi im trying to study for a quiz on user-defined functions. Im trying to run two expressions in one user-defined function and so far its only printing one set of values for each. Is there something wrong with the way im setting the user-defined function or the way im trying to print it out?

Function page:

function results=exfl(x)
term(1)=1.0;
for n=1:100
    term(n+1)=(term(n))*((-1^n)*((x).^(2))*(2*n-1)/(2*n));
    if abs(term(n+1))<=1.0e-7
        break
    end
end
ex1=sum(term);
for i=1:length(x)
   f=(1+x(i)^2)^(-0.5);
end
ex2=sum(f);
results=[ex1',ex2'];

and the next script page:

clc;
fprintf('   x   fx(arithmetic) fx(series)\n');
fprintf('-----------------------------------\n');
x=-.9:.1:.9;
%We must set x as a function of i for the for loop
for i=length(x)
y=exfl(x(i));
fprintf(' %.1f  %10.6f    %10.6f \n',x(i),y);
end
