Algebra Help Please!

Answer 1

Vertex: (-1, -3)

I need to find the shift/change in the vertex from the vertex above (-1, -3) and the vertexes below.

The shift in Vertex (-1, -3) to Vertex: (-1, -1.5)
The shift in the Vertex (-1, -3) to Vertex: (-1/2, -3)
The shift in the Vertex (-1, -3) to Vertex: (-1, -1)
The shift in the Vertex (-1, -3) to Vertex: (1, -3)

Answer 2

@phi

Answer 3

if you have an equation
y = a(x - h) + k
h,k is the vertex

if you want to change the h, add a number inside the parens
if you want to change the k, add a number on the outside

Answer 4

But how would I know the change? Like a shift left, right, up, down, etc.

Answer 5

the first shift is
The shift in Vertex (-1, -3) to Vertex: (-1, -1.5)

the x value stays the same = -1. so the vertex does not move "sideways"
the y value changes from -3 to -1.5. -1.5 is above -3 , so the vertex moved up
it moved up 1.5 steps

Answer 6

So the next 3 would be: The shift in the Vertex (-1, -3) to Vertex: (-1/2, -3)
Shift: .5 down
The shift in the Vertex (-1, -3) to Vertex: (-1, -1)
Shift: 2 up
The shift in the Vertex (-1, -3) to Vertex: (1, -3)
Shift: 2 right?

Answer 7

the 2nd two are good. the first one is a shift in the x direction, not y direction

Answer 8

.5 left for the first one?

Answer 9

0.5 to the right.

-1 to -0.5 moves to the right (-0.5 is on the right side of -1)

Answer 10

It's -1 to -1.5 though. Wouldn't that be to the left?

Answer 11

ok, but the question is
The shift in the Vertex (-1, -3) to Vertex: (-1/2, -3)
should that say -3/2 or -1.5 instead of -½ ?

Answer 12

but if the question is
The shift in the Vertex (-1, -3) to Vertex: (-1.5, -3)
then you are correct, it is a shift of ½ to the left.
