Question

Dada a função F(X)= 14X+ 5,calcule F(2)+F(4)

Answer 1

F(2)= 14*2+5= 33
F(4)=14*4+5= 61

F(2)+F(4)
33+61= 94

Answer 2

Ola!!

Resolução!!

f ( x ) = 14x + 5

• f ( 2 ) = ?

f ( x ) = 14x + 5
f ( 2 ) = 14 • 2 + 5
f ( 2 ) = 28 + 5
f ( 2 ) = 33

• f ( 4 ) = ?

f ( x ) = 14x + 5
f ( 4 ) = 14 • 4 + 5
f ( 4 ) = 56 + 5
f ( 4 ) = 61

f ( 2 ) + f ( 4 ) = ?

= f ( 2 ) + f ( 4 )
= 33 + 61
= 94 → resposta
