Question

How do you find the horizontal asymptote for `4/(1+e^(1-x))`?

Answer 1

`y=4` and `y=0` are horizontal asymptotes

Explanation:

Let `y=4/(1+e^(1-x))`

Try to imagine the value of `y` if `x` is made to increase up to `+oo`

As `x` approaches the value `+oo`
`y` approaches `4`

Try to imagine the value of `y` if `x` is made to decrease down to `-oo`

As `x` approaches the value `-oo`
`y` approaches `0`
