Question

determine o grafico funçao: y=x^2+6x
me ajudem
pls

Answer 1

x²+6x

a= 1 b= 6 c = 0

Δ=b²-4ac

Δ=6² - 4 * 1 * 0

Δ= 36 - 0

Δ=36

x= -b+-√Δ /2a

x= -6+-√36 /2*1

x= -6+-6 / 2

x' = -6+6 /2 = 0/2 = 0

x''=-6-6/2 = -12/2 = -6

Xv= -b /2a -6/2*1 = -6/2 = -3

Yv = -Δ /4a -36/4*1 = -36/4 = -9
