# Math Help - Domain/Range of this e graph

1. ## Domain/Range of this e graph

y = e^3x
Attached is the graph, not sure what domain and range is?

2. Is your function $\displaystyle e^{3x}$ or $\displaystyle e^3x$? Because it looks like you've graphed the second...

3. The image that you posted is of the graph $e^3x$ which is a line.

I suspect you want the graph of $e^{3x}$.

Is that correct?

4. Yeah!
Let me fix the graph..

5. Thanks for helping guys.

Actually I did do the graph wrong, as it is y= e^(3x)

So domain: x equals R
range: y > -1

6. For the range $y\geq 0$
y can never be negative right?

I agree with your domain; also it's not 'x equals R', it's $x \epsilon \mathbb{R}$, meaning x belongs to the set of all real numbers.
