Czy moglby mi ktos pomoc rozwiazac to rownanie funkcji kwadratowej?
f(x) =(-0.5) x^{2} + 3[/tex]
Musze odnalezc wierzcholek oraz miejsca zerowe.

f(x) = -0,5x²+3
f(x) = 0
-0,5x²+3 = 0
a = -0,5, b = 0, c = 3
-0,5x² = -3 /:(-0,5)
x² = 6
x = -√6 v x = √6
MZ: -√6; √6
========
W(p;q)
p = -b/2a = 0
q = -Δ/4a = -(b²-4ac)4a = -[-4(-0,5)·3]/[4·(-0,5)] = 3
W(0; 3)
=======
f(x)=(-0,5)x²+3
-0,5x²+3=0
-0,5x²=-3 /÷(-0,5)
x²=6 /÷√
x=√6 lub x=-√6 Msc₀=√6; -√6
W(p;g) Δ=b²-4ac=0²-4*(-0,5)*3=6
p=-b\2a=0\2*(-0,5)=0
g=-Δ\4a=6\4*(-0,5)=6\2=3
W(0;3)
