Question

Find the equation for a parabola with the vertex of -3,0.

Answer 1

\[(x+3)^2\]

Answer 2

what about a parabola with the vertex 0,0

Answer 3

\[x^2\]

Answer 4

umm 3,0

Answer 5

\[(x-3)\]

Answer 6

0,-2

Answer 7

\[y=a(x-h)^2+k\] is the form for any parabola where a is the slope/direction, and (h,k) is the vertex.

Answer 8

yeah i know but i dont understand how to work them out thats why im asking for help

Answer 9

Well if you want something to be moved along the x axis, then change h. So for the first you wanted x to be -3 so you have to make -h=-3, so h=3. For the second, you wanted both x and y to be 0, so we made h and k both equal to 0.

Answer 10

LOL yeah it is still confusing to me.

Answer 11

okay so i tried to workout the 0,-2 question. what answer did you get? and i will see if i got it right. please

Answer 12

Great, what did you get?

Answer 13

Never mind it is wrong. The way I did it makes no since at all.
