Question

Quais são as coordenadas do vértice ​

Answer 1

Resposta:

$x_v=-\frac{b}{2a}\,\,e\,\,y_v=-\frac{\Delta}{4a}ouf(x_v)\\\assim\\\\V(-\frac{b}{2a},-\frac{\Delta}{4a})$

Explicação passo-a-passo:

Se for de um parábola da forma ax²+bx+c

$x_v=-\frac{b}{2a}\,\,e\,\,y_v=-\frac{\Delta}{4a}ouf(x_v)\\\assim\\\\V(-\frac{b}{2a},-\frac{\Delta}{4a})$
