u can't get negative values..

Answer 6

There is no restriction

Answer 7

How about zero (0)?

zero can be accept

Answer 9

Domain: \(x\;\in\;\mathbb{R}\) -- Zero is in there
Range: \(2^{x} > 0\) -- Zero is not in there.

Answer 10

so,this means that the range should be\[R^{+}\]

Answer 11

@tkhunny how did u that symbol R?

Answer 12

If that doesn't include zero, that's it.

\ m a t h b b { R }

Answer 13

okay,,zero is not included..
so,the range would be\[ \mathbb{R}^{+} \]

Answer 14

Yes. That symbol means all positive real numbers.

Answer 15

okay..
