Question

98- Determine os zeros da raizes das funções:
a) f(x)=2x - 8
b) g(x)= -2x - 20
c) h(x)= 8x + 10​

Answer 1

✔OLÁ!!!

A) F(X) = 2X - 8

0 = 2X - 8

- 2X = - 8 (-1)

2X = 8

X = 8/2

X = 4

B) G(X) = - 2X - 20

0 = - 2X - 20

2X = - 20

X = - 20/2

X = - 10

C) H(X) = 8X + 10

0 = 8X + 10

- 8X = 10 (-1)

8X = - 10

X = - 10/8

X = - 5/4
