По формуле x0 = -b/2a = 5/4 = 1.25
y0= -2*(1.25)^2 + 1.25*5 + 3 = 6,125
A(1.25; 6.125)
(3m³-48)/(3m-6)=3(m³-16)/3(m-2)=(64-16)(-4-2)=48/-6=-8'
(b¹²+b³)/(b⁹+1)=b³(b⁹+1)/(b⁹+1)=b³=-0.5³=-0.125
(4m²-4m+1)/(4m-2)=(2m-1)²/2(2m-1)=(2m-1)/2=(12-1)/2=11/2=5.5
405=100% => 1%=405\100=4.05
332 - 332/4.05 = 81.975%
23 - 23/4.05 = 5.679%
12 - 12/4.05 = 2.963%
38 - 38/4.05 = 9.383%
