what does precal mean I don't understand

Answer 2

ANSWER


`(F)/(G) ( - 1) = - ( 2)/( 3)`

Step-by-step explanation

The given functions are:


`F(x)=2x`

and


`G(x)= {x}^(2) + 2`


`(F)/(G) (x) = (F(x))/(G(x))`


`(F)/(G) (x) = \frac{2x}{ {x}^(2) + 2 }`

Substitute x=-1


`(F)/(G) ( - 1) = \frac{2( - 1)}{ {( - 1)}^(2) + 2 }`


`(F)/(G) ( - 1) = ( - 2)/( 1+ 2 )`


`(F)/(G) ( - 1) = - ( 2)/( 3)`

The first choice is correct.
