Question

algm sabe resolver? a resposta é 23/16​

Answer 1

F(x) = 3x^2 - 3x + 2
F(2) = 3.2^2 - 3.2 + 2
F(2)= 3.4 - 6 + 2
F(2)= 12 - 4
F(2)= 8

F(x) = 3x^2 - 3x + 2
F(-3) = 3.(-3)^2 - 3.(-3) + 2
F(-3)= 3.9 + 9 + 2
F(-3)= 27 + 11
F(-3)= 38

F(x) = 3x^2 - 3x + 2
F(0,25) = ?
0,25= 25/100 (:25)/(:25) = 1/4
F(1/4)= 3.(1/4)^2 - 3.1/4 + 2
F(1/4)= 3.1/16 - 3/4 + 2
F(1/4)= 3/16 - 3/4 + 2
F(1/4)= (1.3 - 4.3 + 16.2)/16
F(1/4)= (3-12+32)/16
F(1/4)= 23/16
F(0,25)= 23/16
