Answer 1

Resposta:

V(2,0)

Explicação passo-a-passo:

$Y = -2x^{2} + 8x - 8\\\\\\Xv = -\frac{b}{2a} \\\\Yv = -\frac{b^{2}-4ac }{4a} \\\\\\Xv =- \frac{8}{2*(-2)} \\\\Xv = -\frac{8}{-4}\\\\Xv = 2\\\\Yv = -\frac{8^{2}- 4*(-2)*(-8) }{4*(-2)} \\\\Yv = -\frac{64 - 64}{4*(-2)}\\\\Yv = \frac{0}{-8} \\\\Yv = 0$
