Пусть f(x) = х2- Зх + 2.Задайте аналитически функцииу1 = f(-x);
у1 = f(-x)=(- х)²- З(-х )+ 2 ⇒у1=(х)²+З(х )+ 2;
у = f(x + 2);
у2 = f(x + 2)=(x + 2)²- З(x + 2 )+ 2 ⇒у2=х²+4х +4-3x-6+ 2=х²+х ;
у2==х²+х ;
у = f(3 - х);
у3 = f(3-x)=(3-x )²- З(3-x )+ 2 ⇒у3=х²-6х +9-9+3x+ 2=х²-3х+2;
у3=х²-3х+2;
у = 4 - f(x)
у4= 4-(х²- Зх + 2)= 2-x²+3x;
у4= 2-x²+3x;
