Question

find the vertex and line of smmetry
F(x)=-2(x+3)^2
this is what i got
the vertex (-2,3)
line of smmetry is 3 am i right???

Answer 1

No, there is a bit mistake.

vertex, (-3,0)
line of sym = -3

Answer 2

how did you get that what about the -2

Answer 3

u can't have -2.

Answer 4

oh ok , why cant you

Answer 5

Good question..
this is b/c the standard form is,

a(x-h)^2 + k

where (x-h)=0 is the x cordinate of the vertex and k is the y cordinate.
