The transformation T: R^2 ---> R^2 which maps the curve with the equation y=x^3 to the curve with the equation y= (3x-6)^3 + 1, could have:

It gives me different answers in the matrix form to choose from (Sorry - I don't know how to type up matrices on this)

I got the dilation from the y axis of 1/3, and for the translation I thought it'd be + [6] but it was actually +[2] .

Maybe I'm suppose to take the '3' out as a common factor and that would leave me with the 2? Could someone correct me please?

Easiest way to type up a matrix is probably do put ` on either side and type it like you would in notepad, with spaces, etc. Hope that helps/makes sense.

Best answer

If you take the 3 out, you get:

y = 3^3(x-2)^3 + 1 = 27(x-2)^3 + 1

Then your matrix is:

[ 1 0 ; 0 27 ]

[x ; y] + [2 1] ( ; represent new lines)
