Question 113512: How do I find the domain and the range for the function f(x)=ex
and express both in interval notation.
NOTE: the (x) following the (e) should be written like expanded notation, I just do not know how to do that on the computer.

I think what you mean is that the x should be exponential notation. In other words, . The way to do that on the computer in plain text is e^x.

Now, you want the domain and the range. We can see this from an examination of the graph of .

From the graph, we can see that the domain (all possible values for x) is all Real numbers, or

The value of can never be zero or negative, so the range is all positive reals, or

Hope that helps,
