respondido por: LaísSouza1997

Zero da função f(x) é quando fazemos f(x) = 0

Se f(x) = 4x - 36 → 4x - 36 = 0

4x - 36 = 0

4x = 36

x = 36/4

x = 9

Zero da função f(x) = 4x - 36 é x = 9

a) -5 -3 -2 -7 + 13 = (-5 -3 -2 -7) + 13 = -17 + 13 = -4 → (Correto)

b) +15 - 20 - 5 + 13 - 1 = (15 + 13) + (-20 -5 - 1) = 28 - 26 = 2 → (Correto)

c) 9 - 12 -3 +2 -1 +7 = (9 + 7 + 2) + (-12 -3 -1) = 18 - 16 = 2 → ops, aqui dá 2 e não -16.
