I need to know what a corresponding point means or is, in terms of:

Suppose the point P(2,3) is on the function f(x). Find the point that corresponds to P on each function; show or explain how you figured this out.

**(a)**f (x + 4)**(b)**f (x) + 3**(c)**-2 f (x)**(d)**1/2 f (x - 5) + 1

and many other places.

Why not have a go at some of the questions, even if you get them wrong. You'll probably get more advice if you show that you've tried and you'll probably learn more as well.

The graph y=f(x+4) is a translation by 4 left of the graph of y=f(x). The point (2,3) is on the graph of y=f(x) and, to answer (a), you need to say what it would be translated to on the graph of y=f(x+4).

The question is really badly phrased and I think would have been clearer if graphs, rather than functions, had been talked about.

i also agree, i mainly don't understand because of the way it's worded. I've been thinking it might be related to the grapgh (like how you explained the shifting) but i'm not sure what a corresponding point means, so i don't really know if what i'm doing is right. But thank you

For c) what is the transformation

-2*f(x)

how would it apply to the quadratic and hence the corresponding P.?
