Question

dada a funçao F(X)=3x+5, calcule
a) F(3)
b)f(-5/3)

Answer 1

Resposta:

Explicação passo-a-passo:

F(x) = 3x + 5

a) F(3) = 3*3 + 5

F(3) = 9 + 5

F(3) = 14

b) F(-5/3) = 3*(-5/3) + 5

F(-5/3) = -15/3 + 5

F(-5/3) = -5 + 5

F(-5/3) = 0

Espero ter ajudado :)

Answer 2

Vamos lá

Calculando a função...

f ( X ) = 3X + 5
_______________

f ( 3 ) = 3 ( 3 ) + 5

f ( 3 ) = 9 + 5

f ( 3 ) = 14
_______________

f ( - 5 / 3 ) = 3 ( - 5 / 3 ) + 5

f ( - 5 / 3 ) = 3 / 1 ( - 5 / 3 ) + 5

f ( - 5 / 3 ) = - 15 / 3 + 5

f ( - 5 / 3 ) = - 5 + 5

f ( - 5 / 3 ) = 0
