Sejam as funções f(x)=X² - 2X +1 e g(x)= 2X + 1
Calcule a) f(g(1))
b) g(f(2))
c) f(f(1))
G(1)= 2x + 1 G(1)= 2.1 + 1 G(1)= 3 F(g(1)) F(3)= 3² -2.3 + 1 F(3) = 9 – 6 + 1 F(3)= 4 F(g(1))= 4 F(2)= x² - 2x +1 F(2)= 2² - 2.2 + 1 F(2)= 1 G(x)= 2x + 1 G(1)= 2.1 +1 G(f(2))= 3 | F(x)= x² -2x +1 F(1)= 1² -2.1 +1 F(1)= 0 F(x)= x² -2x +1 F(0)= 0² -2.0 +1 F(f(1))= 1 |
