A transformation is described through the equation TX+B=X^1
where T=⎡4 0⎤ and B= ⎡-1⎤
⎣0 2⎦ ⎣ 4⎦
Find the image of the curve with equation y=-2x^3+6x under the transformation.
I know how to work out these types of questions when the equation is T(X+B)=X^1, but I'm just not to sure how much differently I will need to do the question.
This is what I was doing:
Therefore you then sub in your matrixes. Once you get an equation for x and y, you then sub them into the straight line equation etc.
Does anyone know if that is the right method?
Thanks in advance.
