Question

achem os zeros da funçao f(x)=x²=-5x+6 e construa o grafico

Answer 1

ax² + bx + c
use a formula de bhaskara

a=1
b=-5
c=6

#² = b² -4ac = 25 -24 = 1
# = 1
X¹ = -b/2a + #/2a = 5/2 + 1/2 = 3
X² = -b/2a - #/2a = 5/2 - 1/2 = 2

Gráfico

x = {0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0}
y = {6.0 3.75 2.0 0.75 0.0 -0.25 0.0.0.75 2.0 3.75 6.0}
