Alissa is analyzing an exponential growth function that has been reflected across the y-axis. she states that the domain of the reflected function will change because the input values will be the opposite sign from the reflected function. simon disagrees with alissa. he states that if an exponential function is reflected across the y-axis, the domain will still be all real numbers. which student is correct and why?

Simon is correct.

Step-by-step explanation:

The domain of a function is the set of x value which a function can take.

Now, consider the provided information.

The exponential growth function has been reflected across the y axis.

The domain of the exponential function is whole real line but its range is only positive real number. If we reflect the graph around y axis the domain and range do not change.

Therefore, Simon is correct.
