Question

Help? I got this wrong.. :(

Answer 1

\[f(x)=\sqrt{1-x}\]

Answer 2

@jdoe0001

Answer 3

I put x>1..

Answer 4

Should it be:
\[x \le 1\] ?

Answer 5

yes

Answer 6

Dadgummit. -_- Thanks..

Answer 7

\[f(x)=\sqrt{1-x}\] has restrictions on its domain in that the quantity under the radical sign must always be 0 or greater than 0.

So we could write the domain as \[1-x \ge 0\] If you'd add x to both sides, the resulting inequality would be the domain of your function f(x).
