Think about what happens the graph of the curve. And then if A is less Reflection Over the X -Axis For our first example let's stick to the very simple parent graph of y = x ^2. f (x)= a(xh)2 +k f ( x) = a ( x h) 2 + k. where (h, k) ( h, k) is the vertex. If you have y = 2(x-5)^2 + 2, the 5 is with the x, so if you want to do the same with the ys, you have to subtract 2 on both sides to get y - 2 = 2(x-5)^2, in this case the y would also have to change signs (similar to the point slope form of a linear equation y-y1=m(x-x1). A ball is thrown straight up from a height of 3 ft with a speed of 32 ft/s. Direct link to Arbaaz Ibrahim's post At about 1:30 minutes int, Posted 4 years ago. wait, do you mean y=(x9)^2 - 1?
