Describe the differences between the graph of y = -3(x + 7)2 - 10 and the standard position graph of y = x2.

Question

$a(x-h)^2+k$ $a$ is a dilation factor that widens the graph if $|a|>0$ and makes it more narrow is $|a|<0$ If the sign of $a$ is negative, the graph does a reflection of itself. the $h$ parameter will shift your graph horizontally. If $k>0$, it will shift to the right, if $k<0$ it will shift to the left. the $k$ parameter will shift the graph vertically. If $k>0$ it will shift it upward, if $k<0$ it will shift it downward.

is that it?

kirbykirby · Answer

oh when I say it does a reflexion, it does a horizontal reflexion to be more precise.

ok anything else

kirbykirby · Answer

pretty much, just use that information with the numbers given to you :)

ok thanks a lot

kirbykirby · Answer

oh in the 2nd paragrpah, I talk about $h$ but wrote k afterward in that same line. It should always be about h!

anonymous · Answer

ok

kirbykirby · Answer

h > 0: shift to the right
h < 0 : shift to the left
