Question

Dada a função f(x)=5x-11 determine

A) F(-19)=
B) F(3,4)=
C) F(2-/7)=

Answer 1

Resposta:

Explicação passo-a-passo:

f(x)=5x-11 determine

A)

f(x) = 5x - 11

F(-19)= 5.(-19) - 11

F(-19)= - 95 - 11

F(-19) = - 106

B)

f(x) = 5x - 11

F(3,4)= 5.3,4 - 11

F(3,4) = 17-11

F(3,4) = 6

C)

f(x) = 5x - 11

F(-2/7)= 5.(-2/7) - 11

F(-2/7) = -10/7 - 11

F(-2/7)= (-10 - 7.11)/7

f(-2/7) = (-10-77)/7

f(-2/7)= - 87/7
