Question

The graph of which equation has a vertex of (-2, 0)?

Answer 1

after you post everything i will help you

Answer 2

u forgot to post the equations!!

Answer 3

A) y = (x - 2)2 + 2
B) y = 3(x + 2)2 + 1
C) y = 3(x - 2)2
D) y = 3(x + 2)2
@helder_edwin @FriedRice
its been a long day so sorry

Answer 4

do you know how to find the vertex from the vertex equation??

Answer 5

i dont... ):

Answer 6

this is the formula y = a(x-h)^2 + k
the question is telling you to just plug in (h,k) or(-2,0)

Answer 7

so y = a(x + 2)^2 + 0

Answer 8

yes.

Answer 9

do yo have the picture of the gragh because they have a slope and i dont know which one can be correct

Answer 10

graph*

Answer 11

which of the equations u gave us looks like what u just wrote?

Answer 12

or replace \(x\) by \(-2\) (in your head) and see which one gives \(0\)

Answer 13

i wasn't given a graph , just a list of equations @FriedRice

Answer 14

u don't need the graph.

Answer 15

D? @helder_edwin

Answer 16

then the answer is D

Answer 17

yes. very good.
