Hi everyone, im having trouble with this question, if you could help me out i would very grateful. The question says the point (3,-4) is on the graph y=f(x). What would be the new point on the transformed graph y-5=2f(3(x-1))???

There's not enough info... we need to know more about f(x). For more solutions to textbook problems, be sure to check out http://www.slader.com/s/eWFrZXlnbGVl. I submit a lot of content there as well. (They even pay you if you help them out to add solutions).

you can solve 
$$3(x-1)=3$$ for x and get 
$$3x-3=3$$
$$3x=6$$
$$x=2$$

anonymous · Answer

so if 
$$x=2$$ then 
$$3(x-1)=3$$ so 
if 

$$x=2$$
you get 
$$f(3(x-1))=f(3)=-4$$and then 
$$2\times -4+5=-3$$ so the new point on the graph will be 
$$(2,-3)$$
