I just got back from writing my grade 12 math final and I figure I did really well. There was only one question that stumped me, and it was freaking stupid, too. So the problem was this:

There was a picture of [tex]y=x^{3}[/tex] and the points P(2,8) was labelled. The question was where does the point P go if the graph is expanded horizontally by a factor of 3about the line x=4... What the hell did they mean? I thought they meant that you first shift the graph over 4 places to x=4 and then you would apply the transformation, the point would end up being Q(10,8) but that wasn't even on there.

Here were my choices...

A.(8,8)

B.(14/3,8) (I think)

C.(10/3,8)

D.(-2,8)

I ruled out D pretty quickly and went with A... but it didn't make any sense. Did I get it wrong?

Pretty sad the the only question that stumped me was a transformation question...
