Question

How do you find the domain and range of `F (X) = (x-2)/(x+4)`?

Answer 1

The only domain restriction is that `x!=-4`

Explanation:

This would make the numerator `=0` (not allowed)

As `x` grows larger, the `-2and+4` make less difference, so the function will get closer and closer to `x/x=1`, without reaching it.
So range is restricted to `F(x)!=1`
graph{(x-2)/(x+4) [-36.55, 36.55, -18.25, 18.26]}
