Question

Find f(-5) if f(x)=|x+1|

Answer 1

f(x)=|x+1|
f(-5)=|-5+1|
f(-5)=|-4|
f(-5)=4. As a result, f(-5)=4 is the correct answer. Hope it help!

Answer 2

`f(-5)=4`

Explanation:

we have

`f\left(x\right)=\left|x+1\right|`

we know that

`f(-5)` is the value of the function for the value of
`x=-5`

so

Substitute the value of
`x=-5` in the function

`f\left(-5\right)=\left|-5+1\right|`

`f\left(-5\right)=\left|-4\right|=4`

`f(-5)=4`
