Question

determine o zero de cada função afim​

Answer 1

Olá!

a) y = 2x - 12

2x - 12 = 0

2x = 12

x = 12 ÷ 2

x = 6

b) y = 6x + 2

6x + 2 = 0

6x = -2

x = $-\frac{2}{6}$

x = $-\frac{1}{3}$

c) y = -3x + 15

-3x + 15 = 0

-3x = -15

x = $\frac{-15}{-3}$

x = 5

d) y = -4x - 2

-4x - 2 = 0

-4x = 2

x = $\frac{2}{-4}$

x = $-\frac{1}{2}$
