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 \( h(x) = 1.2x \).
This statement is accurate because exponential functions, like \( 1.2^x \), grow faster than linear functions, like \( 1.2x \), as \( x \) increases. Therefore, while at smaller values of \( x \), \( h(x) \) may be larger, \( j(x) \) will eventually exceed \( h(x) \) as \( x \) becomes large.
