To accurately evaluate the comparison of the growth rates of \( g(x) = 1.3^x \) and \( f(x) = 1.3^x \) (which are actually the same function), Austin should look at the functions and their properties directly.
Since both functions are identical, they will always have the same value for any given \( x \). Therefore, their curves will be on top of each other for all \( x \) values, and there will not be a point where one curve is above the other.
Given this information, the correct interpretation is: Austin should find where one curve is above the other curve on the graph. The growth rate of f(x) = 1.3^x is only greater than the growth rate of g(x) = 1.3^x to the right of their right-most intersection point.
However, since they are the same function, the statement technically holds no validity; instead, Austin would observe that \( f(x) \) and \( g(x) \) are equal for all \( x \). Therefore, a more accurate statement could be, "Austin should observe that both functions are identical and will not differ at any point."
