### HELP WITH INPUT OUTPUT FUNCTIONS

What is F(-2)? if your answer is not a whole number, write it as a fraction in lowest terms, using the slash mark (/) as the fraction bar.

F(x) = 2x+3/xxx-5

It is not so clear what is the function.
I suppose the function is:

$F(x) = \frac{2x + 3}{xxx - 5}$

$F(-2)$ means to replace in the fraction $x$ with $-2$

$F(-2) = \frac{2*(-2) + 3}{(-2)(-2)(-2) - 5} = \frac{1}{13}$
