The correct statement regarding Liam's comparison of the growth rates of the functions \( h(x) = 1.2^x \) and \( j(x) = 1.2^x \) is the following:
Liam should compare the rates of change of the terms in both sequences. The growth rate of j(x) = 1.2^x will quickly surpass the growth rate of h(x) = 1.2^x.
This statement accurately reflects that both functions represent the same exponential growth. However, since \( h(x) \) and \( j(x) \) are identical (both being \( 1.2^x \)), it indicates that their growth rates are equal rather than one surpassing the other. Therefore, Liam will observe that the growth rates of both functions are equivalent at all points.
