Answer: D, -1
First, plug in the value -1 for x in f(x) first. [tex] \frac{1}{(-1)^2+1} [/tex] can then be simplified to [tex] \frac{1}{2} [/tex] because [tex](-1)^2=1[/tex]. Next, put the value -1 for x in the equation g(x). This will look like [tex]- \frac{1}{2} [/tex].

The final step is to evaluate f(x) divided by g(x). f(x) = 1/2 and g(x) = -1/2, so when divided, you get -1.
bcalle
f(-1)= 1/2
g(-1) = -1/2
1/2 / -1/2 =
1/2 * -2/1 = -1
