Answer 2

answers

y = (x − 3)2 − 1
y = (x + 3)2 − 1
y = (x − 4)2 − 2
y = (x − 4)2 + 8

Answer 3

help me please @ganeshie8

Answer 4

please someone anyone help me

Answer 5

please anyone help me understand how to do this
please

Answer 6

Look at the graph, what are the coordinates of vertex?

Answer 7

did you get it?

Answer 8

the of the vertex would be ( -3,-1)

Answer 9

Yes, remember the vertex form of parabola ?

Answer 10

it's \[y =a \left( x-h \right)+k\]

Answer 11

yea good job

Answer 12

\[y =a \left( x-h \right)^2+k\]

Answer 13

where the vertex is \((h,~k)\)

Answer 14

plug in the vertex coordinates in above equation

Answer 15

\[y=a \left( x-\left( -3 \right) \right)^{2}-1\]

Answer 16

good, which is same as
\[y=a \left( x+3\right)^{2}-1\]

Answer 17

look at the options

Answer 18

oh it's the second answer right

Answer 19

Correct! good job!`
