Question

Identify the vertex for the graph of y = −3x2 + 6x − 4.

Answer 1

the vertex of the graph is -b/2a

Answer 2

a = -3
b = 6
c = -4

Answer 3

-6/-6

Answer 4

vertex=1

Answer 5

no that is the x now you got to plug it into the x and find y

Answer 6

to be more exact the x coordinate of th vertex = -b/2a

Answer 7

so the vertex is (1,-1)

Answer 8

Can u do another

Answer 9

Identify the vertex for the graph of y = 2x2 + 8x − 3.

Answer 10

@cwrw238 you can do this one

Answer 11

ok let me try

Answer 12

best if you try yourself

Answer 13

-4,4

Answer 14

-b/2a =
-8 / 4 = -2
x is -2

and y = 2(-2)^2 -16 -3

Answer 15

so that (-2,-11)

Answer 16

ok?

Answer 17

another way to do these is to convert the equation into vertex form

2x2 + 8x − 3. = 2(x"2 + 4) - 3
= 2(x + 2)^2 _ 8 - 3
= 2*x + 2)^2 - 11

the x value of the vertex is when x+2 = 0 and the y value is -11

= (-2,-11)

Answer 18

* = 2(x + 2)^2 - 11
