The domain of each of the following functions is the set of values of x for which the algebraic expression has meaning. Find their ranges.
1) F(x)= 1/1+e^x
2)f(x)=e^√x
3) f(x)=e^-x2
4) f(x)= √sinx
Thank you in advance for your help!
Your formatting is ambiguous, so I hesitate to be specific.
Where are you stuck? You know that you can't have negatives inside square roots or logs, you can't have zero for a denominator or inside a log. How have you applied this information? How far have you gotten?
Please be complete. Thank you!
