Question

what would be formula of this graphic (y=x^2-1)
if you move 2 units to the left and 3 units up.

can i have some help i think is ti y+2=x^2+2 am i right or wrong please help.

Answer 1

y=a(x-h)^2+k is the vertex form of a parabola
if h>0 we move it right h units
if h<0 we move it left h units
if k>0 we move it up k units
if k<0 we move it down k units
Example
y=(x+3)^2+4 is the graph of y=x^2 moved left 3 units and up 4 units
Example
y=(x+2)^2-4 is the graph of y=x^2 moved left 2 units and down 4 units
Example
y=(x-2)^2 is the graph of y=x^2 moved right 2 units

Answer 2

So if you are moving it from left to right you are changing the inside of that square thing
so can you tell me what the inside of that square thing will look like if we move from 2 units the left?

Answer 3

yeah i would be x^2+2-1 = x^2+1 am i right?

Answer 4

no..
the thing inside the square should change since we are moving left/right

Answer 5

we will deal with outside when you can figure out the inside
