For the function
f =@(x) exp(x./2)-2.*x.^2+x+10
how can i construct the exact Taylor Polynomial of 4th degree around x = 2?

This will then be the correct? EDU>> taylor (exp(x./2)-2.*x.^2+x+10,x,2)
I have to give syms x before it will accept the command. Will this affect my wish to go for x = 2?
thanks again!
