Question

dada a funcao y=5x-8, calcule f(2/3):

Answer 1

Explicação passo-a-passo:

dada a funcao y=5x-8, calcule f(2/3):

y(2/3)=5.(2/3)-8

y(2/3)=10/3-8

y(2/3)=10-80/3

y(2/3)=-70/3

espero ter ajudado !

boa tarde !

Answer 2

f(2/3) = 5.2/3 - 8 = 10/3 - 8 = 10 - 24/3 = -14/3

Portanto f(x) = 5x - 8, quando x = 2/3, y = -14/3
