I cannot get this one, Sal in the video explained that when we shift h units to the right we substract h units from the function. The reason the graph shifts up instead of down when you subtract a number from y is because (if you think about it) subtracting from y is the same as adding that number to the opposite side of the equation which results in a. gives you a good way of how to shift and B. down, 6. It only gets you to y minus k. So y must be k higher than this. to the right by h. Now let's think of another must be k higher than this. ( 2 votes) to the right by three, the next step is to shift down by four, and this one is little bit more intuitive. Explain the steps you would use to determine the path of the ball in terms of a transformation of the graph of y = x2. In this case, this is a function because the same x-value isn't outputting two different y-values, and it is possible for two domain values in a function to. Why does this make sense?
