Which steps transform the graph of y=x^2 to y=-2(x-2)^2+2.
a) translate 2 units to the left translate down 2 units stretch by factor 2
b)translate 2 units to the right translate up 2 units stretch by the factor 2
c)reflect across the x-axis translate 2 units to the left translate down 2 units stretch by the factor 2
d)reflect across the x-axis translate 2 units to the right translate up 2 units stretch by the factor 2

Can someone please help me, not sure how to do this problem.

  1. Looks like D to me

    Technically, the stretching is done before the translation. Otherwise the coordinates of the vertex would also be scaled.
