Question

Dada fincao f: r r definida por f(x)= x2 -3x+2 calcule f(0). F(1), f(-1), f(2)2

Answer 1

Resposta:

Explicação passo-a-passo:

(x)= x^2 -3x+2 calcule:

f(0)= 0^2 - 3.0 + 2

F(0) = 2

F(1) = 1^2 - 3.1 + 2

F(1) = 1 - 3 + 2

F(1) = - 2 + 2

F(1) = 0

F(x) = x^2 - 3x + 2

f(-1) = (-1)^2 - 3.(-1) + 2

F(-1) = 1 + 3 +2

F(-1) = 6

f(2) = 2^2 - 3.2 + 2

F(2) = 4 - 6 + 2

F(2) = - 2 + 2

f(2) = 0
