Question

what's the inverse of f(x)=|x+3| ??
x is > or = to -3

Answer 1

Since \(x\geq -3\) then \(|x+3|=x+3\).
For \(y=x+3\) then \(x=y-3\).
So \(f^{-1}(x)=x-3\)

Answer 2

Thank, I'm always nervous about absolute value

Answer 3

Thank you*

Answer 4

watchmath got a second?

Answer 5

sure, where do you want to talk?

Answer 6

i want you to check a rather easy probability problem i just did which doesn't correspond to any of the multiple choice anwers the student gave.
