Plot function with two arguments

I want to plot the function f. It is defined as followed:

f[x_, k_] := (k*x^2 - x)/(x - k)

As you see, it takes two arguments. In fact it shall represent a family of
curves, but I didn't find any way different to this to define one.

My aim is to plot the function by plot firstly f[x, -3], then f[x, -2], f[x,
-1], f[x, 0], ...
Is there a way to do this automatically without typing every single function
with k adjusted. I imagined something like {{x,-20,20}, {k,-3,3}} or so.

Many thanks
and best regards
