Question

formula to find the vertex of y=2(x+1)square-1

Answer 1

Vertex for being y=a(x-h)^2 +k, you just need to plug in the numbers and do the math

Answer 2

I don't really get you question, are you trying to find the vertex?

Answer 3

normaly i m using -b over 2a to find the vertex, where should i use at here?

Answer 4

it depends on what you are trying to find.

Answer 5

the vertex. I know y=(a)square+bx+c using -b over 2a to find the vertex, but how could i find the vertex at here?

Answer 6

well, the equation is already in vertex form, so just solve.

Answer 7

i don't get. I know the vertex is (-1,-1). But I need to show how i find the vertex

Answer 8

hang on, lemme put it in geo gebra

Answer 9

kk

Answer 10

that's it, the vertex is at( -1 -1) you had it. You just need to show how you get it?

Answer 11

yes, that is what i m asking

Answer 12

Well, how i did it is i put the equation into my graphing software and the lowest point of the graph is the vertex
