Question

Given g(x) = -x - 2, find g(3).

Answer 1

`\boxed{\sf g(3) = -5}`

Given:

g(x) = -x - 2

To Find:

g(3) i.e. g(x) where x = 3

Explanation:

`\sf Evaluate \ -x - 2 \ where \ x = 3:`

`\sf \implies - x - 2 = - 3 - 2`

`\sf - 3 - 2 = - (3 + 2) :`

`\sf \implies - (3 + 2)`

`\sf 3 + 2 = 5 :`

`\sf \implies - 5`

Answer 2

g(3) = -5

Explanation:

g(3) is basically the value of g(x) when x = 3. Therefore, g(3) = -3 - 2 = -5.
