To complete the sentences regarding the functions \( f(x) = 6x + 9 \) and \( g(x) = 3(3^x) \), we can analyze their behavior for small and large values of \( x \).
For small values of \( x \), the function with greater values is \( f(x) \). For instance, when \( x = 0 \), \( f(0) = 6(0) + 9 = 9 \) whereas \( g(0) = 3(3^0) = 3(1) = 3 \). As the value of \( x \) increases, however, \( g(x) \) eventually has greater values.
This unequal growth rate happens because \( g(x) \) grows exponentially while \( f(x) \) is a linear function.
Thus, the completed sentences would read:
