Question

Determine os zeros das funções a seguir: a)h(x)=-2x+10 b)g(x)=2x+10

Answer 1

Oie, Td Bom?!

>>> Resolvendo as expressões.

a)

$h(x) = - 2x + 10$

>>> Substitua: $h(x) = 0$ .

$0 = - 2x + 10$

$2x = 10$

$x = \frac{10}{2}$

$x = 5$

b)

$g(x) = 2x + 10$

>>> Substitua: $g(x) = 0$ .

$0 = 2x + 10$

$- 2x = 10$

$x = \frac{10}{ - 2}$

$x = - \frac{10}{2}$

$x = - 5$
