This doesn't seem to be a MATLAB question. Can it be? Like, do you want to plot the actual function and then try different numbers of terms and see how well they look like the original function?

Dear Dav, here is the code to do it up to fifth order:
syms a b x y
y = (a + b * x)^(1/2);
TaylorSeries = taylor(y);
disp(TaylorSeries)
