Sejam as funcoes f(x)= x² -2x +1 e g(x)= 2x +1, calcule




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
