Question

Dada a função g(×)=-5×ao quadrado +6×+8,determine G(1 sobre 2

Answer 1

Olá!!!

Resolução!!!

g ( x ) = 5x² + 6x + 8

• g ( 1/2 )

g ( x ) = 5x² + 6x + 8
g ( 1/2 ) = 5 • ( 1/2 )² + 6 • ( 1/2 ) + 8
g ( 1/2 ) = 5 • 1/4 + 6/2 + 8
g ( 1/2 ) = 5/4 + 3 + 8
g ( 1/2 ) = 5/4 + 11
g ( 1/2 ) = ( 5 + 44 )/11
g ( 1/1 ) = 49/11

Espero ter ajudado!!!
