There is no 'x' in your expression inside symsum(). I guess you are tyring to plot taylor series of exp(x). Try this
syms n x
F = symsum(x^n/factorial(n),n,0,5);
fplot(F, [0 2])

Where is 'x' in your series?

Can you show the mathematical form of your equations?

If you just want to plot 1/n! then you will just get a straight line becuase there is no dependency on 'x'
syms n x
F = symsum(1/factorial(n),n,0,5);
fplot(F, [0 2])

But the original question had a reference to symsum() and x range from [0 2], so that was confusing. If you just want to plot 1/n! then you can do it like this
n = 1:5;
y = 1./factorial(n);
plot(n, y)

But how do you define the polynomial from the series of 1/n!. If you look at my original answer. It does create a polynomial.
