Justifying an Argument 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? Alissa is correct because the domain will change from negative to positive x-values. Alissa is correct because a reflection across the y-axis will change the possible input values of the reflected function. Simon is correct because even though the input values are opposite in the reflected function, any real number can be an input. Neither student is correct.
