Question 115231: If h(x) = f(x) – 3, what would the new coordinates of P be after the shift? I need an anser in (x,y) form. The instructor would talk about the problems, but I am one where you see one, then I can do one. Please help. Thank you.

Since f(x) is really "y", this means h%28x%29=y-3. So what this transformation does is shift every point down 3 units.

So let P be the point (2,3)

Here's the point (2,3)

Now shift the point 3 units down




So our new point is (2,0)


So for any P in general, the coordinates are (x,y-3) where x and y could be any number.
