Question

DERTEMINE O VERTICE DAS FUNÇOES ABAIXO ME AJUDEM    Y(X)=X2-4X+3   F(X)=-X2+16  Y(X)=2X2-4X+2   F(X)=X2-2X  

Answer 1

Para Y(X)=X2-4X+3
$x_{v}$=$\frac{-b}{2a}$=$\frac{4}{2.1} =2$
$y_{v} = \frac{-delta}{4a} = \frac{-4}{4.1} =-1$
V(2,-1)
para F(X)=X2+16
tex] x_{v} [/tex]=$\frac{-b}{2a}$=$\frac{0}{2.1} =0$
$y_{v} = \frac{-delta}{4a}=[tex] \frac{64}{4.1} =16$
v(0,16)

Para y(x)=2X2-4X+2
$x_{v}$=$\frac{-b}{2a}$=$\frac{4}{2.2} =1$
$y_{v} = \frac{-delta}{4a} =[tex] \frac{0}{4.2}$=0
V(1,0)

ParaF(X)=X2-2X
$x_{v}$=$\frac{-b}{2a}$=$\frac{2}{2.1} =1$
$y_{v} = \frac{-delta}{4a} =[tex] \frac{-4}{4.1} =-1$
V(1,-1)
