Oh, OK...I see what is meant

 

The correct answer is the third one.... we have

 

f(x)  =  (3x - 6) / (2 - x)

 

 We can factor a negative out of the denominator thusly : 

 

f (x)   =  (3 x - 6) / - (x - 2)     

 

Factor the numerator

 

f(x)  = 3 (x - 2) / / - (x - 2)     

 

 "Cancel"  the (x -2) term, move the negative to the 3   and we have

 

f (x )  = -3

 

Which is the same as saying    y  = -3    which is what your graph shows....!!!
