Question

If X = (4,0) what does X' equal if Dz,2?

Answer 1

Dz ?

Answer 2

I don't get it either. That is just what the problem said.

Answer 3

Hmm maybe:

X = x(x -4)

X = x^2 - 4x

X' = 2x - 4

X' = 2(x-2)

But i'm not sure what Dz is ment to mean. Is the above the sort of stuff you've been doing?

Answer 4

Yes it is, that is why I don't understand why the Dz suddenly came up. Thank you though!
