Simple question. Say I have 1/x^2, and I were to dilate it 'from the y-axis' by a factor of 2 units. Do I get 1/2x^2?

I'd say yes. But these 'from y-axis/parallel to y-axis' terms always confuse me.

Oh well that makes it pretty easy doesn't it. So the correct answer would be 2/x^2. Thanks very much
Are you sure?
