Hi @sura
Are you looking for something like this?
syms x
sympref('PolynomialDisplayStyle', 'ascend');
f = erfc(x); % function
T = taylor(f, 'Order', 8) % Taylor series
xd = -2:0.1:2;
yd = subs(f, x, xd);
fplot(T, [-2, 2])
hold on
plot(xd, yd, 'r-.'), grid on
title('Taylor approximation vs. actual function')
legend('Taylor','Function')

If you had studies Sam Chak's answer, you would have seen that your series expansion is just the one that he used for the plot.
