Odpowiedź:
a]
f(×)= x²-2x-20 a=1 b=-2 c=-20 p=-b/2a= 2/2=1
q=f(p]= 1²-2*1-20= -21
f(×)= (x-1)²-21
b]
f(×)= -2x²+4x+20 a= -2 b=4 c=20 p= -4/-4=1
q=-2*1+4*1+20=22
f(×)= -2( x-1)²+22
Szczegółowe wyjaśnienie:
a) f(x) = x²-2x-20
p= -b/2a = 2/2 = 1
q = f(1) = 1-2-20 = -21
postać kanoniczna:
f(x) = (x-1)² - 21
b) f(x) = -2x²+4x+20
p = -4/(-4) = 1
q = -2+4+20 = 22
f(x) = -2(x-1)² + 22
