Second option: ![y0](/tpl/images/0537/8086/13750.png)
Step-by-step explanation:
The given function is
![y=e^{4x}](/tpl/images/0537/8086/c2cbf.png)
Remember that the range is the set formed by y-values, that is, the dependent variable elements.
If you think this through, you would deduct that a power cannot be equal to zero or a negative number. All powers are always positive and greater than zero, because the least power that can exist is equal to one, which is
.
Therefore, the right answer is
, because that's the restriction of exponential expression by definition.
