Sketch the graph of f by hand and use your sketch to find the absolute and local maximum and minimum values of f.
18. f(x) = 1/x , 1 < x < 3
I can graph it just fine, but for my answer I got that the function has none of the above. Is this correct?

you are correct. It has a vertical asymptote at x=0 and shoots off up and down forever
