To compare the growth rates of the functions \( h(x) = 1.2x \) (a linear function) and \( j(x) = 1.2^x \) (an exponential function), Liam should note that exponential functions typically grow faster than linear functions as \( x \) increases.
Among the provided statements, the following is the correct one:
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 accurately describes that the exponential growth of \( j(x) \) will eventually exceed the linear growth of \( h(x) \) as \( x \) becomes larger.
