Question

Determine as coordenadas do vértice da parábola f(x)=5x²+x

Answer 1

$x_v=- \frac{b}{2a} =- \frac{1}{2.5} =- \frac{1}{10} y_v=- \frac{\Delta}{4a}=- \frac{1^2-4.5.0}{4.5} =- \frac{1}{20}$

Answer 2

Oi 

5x² + x

a = 5, b = 1, c = 0

delta
d² = 1

vértice

Vx = -b/2a = -1/10
Vy = -d²/4a = -1/20
