You're plotting one point at a time there, which won't appear unless you use a data marker. And even then you'll only see the last one without turning hold on
% F = input('Value for F: ')
F = 3;
figure()
hold on % hold on to see all the points
for i = .05:.05:.95
term = F*((1/(1-i)^1)^.8+11*(1/i)^.4);
fprintf('Cost is %4.1f for Xa %1.2f\n', term,i)
plot(term,'o') % data marker
end
There you go - there's a plot of all the term values.
I imagine it would be better to plot the term values as a function of i, which might look like this:
figure()
hold on
for i = .05:.05:.95
term = F*((1/(1-i)^1)^.8+11*(1/i)^.4);
fprintf('Cost is %4.1f for Xa %1.2f\n', term,i)
plot(i,term,'o')
end
And it might be better still to plot them in a single line, so make the variable term a vector and plot it after the loop:
figure();
i_vector = 0.05:0.05:0.95;
for i = 1:numel(i_vector)
term(i) = F*((1/(1-i_vector(i)))^0.8+11*(1/i_vector(i))^.4);
fprintf('Cost is %4.1f for Xa %1.2f\n', term(i), i_vector(i))
end
plot(i_vector,term)

No for-loop needed.
i = .05:.05:.95;
F = 10;
term = F*((1./(1-i).^1).^.8+11*(1./i).^.4);
plot(term)
