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 look at how the sequences behave as \( x \) increases.
The correct approach is to compare the rates of change, specifically noting that the exponential function \( j(x) = 1.2^x \) will eventually surpass the linear function \( h(x) = 1.2x \) due to the nature of exponential growth compared to linear growth.
Thus, the most accurate response would be:
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 \( h(x) = 1.2x \).
