Question

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

Answer 1

a) f(x) = 2x - 8

2x - 8 = 0

2x = 8

x = $\frac{8}{2}$

x = 4

b) g(x) = - 2x - 20

- 2x - 20 = 0

2x = - 20

x = $\frac{-20}{2\\}$

x = - 10

c) h(x) = 8x + 10

8x + 10 = 0

8x = - 10

x = $\frac{-10}{8}$

x = - 1,25
