    I am assuming 2 things: 1 that by excluded values you mean values not in the domain of this function (ie, things that will make the denominator 0) and also that the denominator is y^2+4y-32.

    If I have assumed correctly, then you need to solve the equation y^2+4y-32 to get the answer. This factors into (y-4)(y+8)=0 so y-4=0 or y+8=0 and you get y=4 or y=-8, so c is correct.
