Question

2.
Determine a raiz ou zero de cada função:
a) Y = 3x - 15
b) Y = 2x + 8
c) Y = 5x - 20
d) Y = 4x + 12
e) Y = 3x - 9
f) Y = 10x - 50

Answer 1

Resposta:

a) y = 3(x-5) → x = 5

b) y = 2(x+4) → x = -4

c) y = 5(x-4) → x = 4

d) y = 4(x+3) → x = -3

e) y = 3(x-3) → x = 3

f) y = 10(x-5) → x = 5
