Question

Dada a equaçao f(x) = -6x²- x + 1 =0 encontre o vertice da parabola

Answer 1

Y= aX² + bX +c. Xv = -B/2a Yv= △/4a

Y= -6X² -X + 1
△ = -b² - 4ac
△ = – (–1)² – 4 × (–6) × 1
△ = 1 - (– 24)
△ = 25

Xv = –1/2×(–6)
Xv = – 1 (-1) /–12 (-1)
Xv = 1/12

Yv = 25/4×(–6)
Yv = 25/ - 24 (-1)
Yv = 25/ 24
