HELP with graphs: y = -2x(x + 3)(x - 4)^2, etc.

[Guest]

how do i know what the graph will look like based on each of these equasions, all the instructions tell me is to sketch the graphs... and im not sure how
y=-2x(x+3)(x-4)^2
f(x)=(x-3)^2 (x+4)^3
12=(x-3)^2+(y+2)^2
i just need to know what types of graphs each one of these would be! THANK YOU

What do you mean by "what it looks like"? What, exactly, do the instructions require you to do? Are you graphing? Finding a transformation? Describing end behavior?

Please reply with the full and exact text of the exercise(s), the complete instructions, a detailed description of any required graphic(s), and a clear listing of what you have tried thus far. An outline of topics recently covered in class would probably be helpful, too.

Thank you.
