Your teacher wrote it wrong, you are correct, it should have been x'/4 there. To check just in case, I put in the formula your teacher derived and reverse all the other transformations except for the dilation part, just to compare the two graphs. You can see it is only being dilated by 2 (evident by the y-intercept), which is wrong. Good job spotting that error! If you correct that error, the final answer should be y' = -(x'/16)^2 - 2
