How do I get A and B fitting coefficients after fitting a power law curve using fit function

Hi I am trying to extract fitting coefficient from f.

x=[100,200,300,400,500,600,700,800]';

y=[5, 14, 16, 17, 18,19, 21, 22]';

f=fit(x,y, 'power1');

f is something like this:

f =

     General model Power1:
     f(x) = a*x^b
     Coefficients (with 95% confidence bounds):
       a =      0.9937  (-0.2434, 2.231)
       b =       0.467  (0.268, 0.666)

I need to extract this a and b value. How can I get that?

Thanks.
