quadratic equation in vertex form \[ y=a(x-h)^2+k\] where k = horizontal shift h=vertical shift (hint: inside the parentheses )

so it would be c?

\[\huge\rm y=a(x-\color{reD}{h})^2+\color{blue}{k}\] h is inside the parentheses not k

yup

oh, so it would be a?

c

what?
Loser66
  • Loser66
(x+h) , this h is adding to x, right? hence the graph moves along x-axis, that is it moves to the right/ left
Loser66
  • Loser66
if f(x) + k, that is the whole graph + k. It means the whole graph (y) moves along y axis. Got what I meant?

\(\huge\rm y=a(x-\color{reD}{h})^2+\color{blue}{k}\) \(h\ne 0\) means horizontal shift, \(k\ne 0\) means vertical shift, example: |dw:1439822841978:dw|

* graph should be (x-5)^2+1
