Question

Given:F(x)=2x and G(x) =X^2+2 find F/G(-1) A)-2/3
B)-2
C)2/3

Answer 1

A) -2/3

Explanation:

To find the answer look at what it's asking you to do. (f/g) means to divide f(x) by g(x).

`(f/g)(x)=(2x)/(x^2+2)`

Now you need to find (f/g)(-1). Plug in -1 wherever there is an x and simplify.

`(f/g)(-1)=(2*-1)/((-1)^2+2)\\ (f/g)(-1)=(-2)/(1+2)\\ (f/g)(-1)=(-2)/(3)`

Your answer is -2/3
