Note, NSS....we have a vertical asymptote at x = 3
So....we cannot put 3 in the denominator of the rational function because this makes the denominator = 0.....so....the last two answers are likely candidates
Note that y = 2/ ( x - 3) looks like this : https://www.desmos.com/calculator/mhbrjflsb8
But....our function is shifted down....so... the "-6" as the second term will shift this down 6 units
So.....the third answer is correct
Does that make sense??
