Question

determine os zeros ou raizes das funcőes: a)f(X)=4x-8 b) g(x)=2x-20 c) h(x)=8x+10​

Answer 1

Resposta:

A) 4x -8 = 0

x= 8/4

x= 2

B) -2x -20 = 0

x = 20 / -2

x= -10

C) 8x+10 = 0

x = -10/8

x = -5/4

Answer 2

Resposta:

A) 4x -8 = 0 x = 8/4

x = 2

B)-2x -20 = 0 x = - 10

x = 20/- 2

C) 8x + 10 = 0

x = - 10/8

x = - 5/4
