To compare the growth rates of the functions \( h(x) = 1.2^x \) and \( j(x) = 1.2x \), Liam should focus on the nature of these functions. The function \( h(x) = 1.2^x \) is an exponential function, while \( j(x) = 1.2x \) is a linear function.
As \( x \) increases, exponential functions generally grow faster than linear functions. Therefore, Liam should compare the rates of change of the terms in both sequences. Specifically, he will observe that the growth rate of \( h(x) = 1.2^x \) will quickly surpass the growth rate of \( j(x) = 1.2x \).
The correct statement based on this explanation is:
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 \( h(x) = 1.2x \).
