Question

How do you find the domain and range of `h(x)= 1/(x+1)`?

Answer 1

Domain is `RR , x != -1`
Rage is `RR , h(x) != 0`

Explanation:

`h(x) = 1/(x+1)`
Domain: Denominator must not be `0 :. x+1 != 0 or x != -1`
Domain is any real value except `-1`
So Domain is `RR , x != -1`

Range is any real value except `0`
So Rage is `RR , h(x) != 0` graph{1/(x+1) [-10, 10, -5, 5]}[Ans]
