    the denominator is (x-3)(x+1) so you can see now that it will change signs at 3 and -1 has no mimimum and no maximum.

    ohh ok, it is increasing till -1, (at -1 it has no value) than decreases till 3 (where it again has no value) and it decreases after that too. There are jumps in this function. try to draw it. I have it in my head now, but it would help.

    ok so tell me if this is right: increasing: (-infinity,-1) decreasing:(infinity,3) minimum:none maximum:none

    decreasing (-1, infinity) and at 3 it jumps up from -infinity to +infinity

    what you wrote increasing: (-infinity,-1)

    just think about values of the functions and where it changes signs
