Question

Dado a função f ( x ) = 3x² - 7x + 10. Calcule f ( 2 ) + f ( 4 )

Answer 1

Dado a função
f ( x ) = 3x² - 7x + 10
Calcule f ( 2 ) + f ( 4 )
F(2)= 3.(2)^2 - 7.2 + 10
F(2)= 3.4 - 14 + 10
F(2)= 12 - 4
F(2)= 8

F(4)= 3.4^2 - 7.4 + 10
F(4)= 3.16 - 28 + 10
F(4)= 48 - 18
F(4)= 30

F(2)+f(4)= 8+30 = 38

R.: 38
