27x^2- is this a dilation of a factor of 27 from the x intercept and a dilation of 1/27 from the y intercept?
can be considered a transformation of in two different ways:
1. - dilation by a factor of 27 in the vertical direction, that is, from the x-axis.
2. - dilation by a factor of in the horizontal direction, that is, from the y-axis.
1. is the way that most folk would think of it.
