Question

y= x²+ 4x + 4 alguém sabe o vertice????????????????

Answer 1

V= ( -b/2a , -∆/4a) <=> V=( -2, 0)

Xv= -4/2.1
Xv= -4/2
Xv= -2

Yv= -(4²-4.4.1)/4.1
Yv= -(16-16)/4
Yv= 0/4 = 0

Answer 2

y=x^2+4x+4


a=1


b=4

c=4


∆=b^2-4.a.c

∆=(4)^2-4.(1).(4)

∆=16-16

∆=0

yv=-∆/4a

yv=-0/4.(1)

yv=0/4

yv=0

xv=-b/2a

xv=-4/2.(1)

x v=-4/2

xv=-2

V={-2,0}

espero ter ajudado!

bom dia!
