Question
Liam is using sequences to compare the growth rates of h(x)=1.2x and j(x)=1.2x. Which statement correctly describes how Liam should do this and what he will observe?(1 point)
Responses
Liam should look at where one sequence has terms greater than the terms in the other sequence. The growth rate of h(x)=1.2x is greater than the growth rate of j(x)=1.2x when its terms are greater.
Liam should look at where one sequence has terms greater than the terms in the other sequence. The growth rate of h left parenthesis x right parenthesis equals 1.2 x is greater than the growth rate of j left parenthesis x right parenthesis equals 1.2 superscript x baseline when its terms are greater.
Liam should compare the rates of change of the terms in both sequences. The growth rate of h(x)=1.2x will quickly surpass the growth rate of j(x)=1.2x.

Liam should look at where one sequence has terms greater than the terms in the other sequence. The growth rate of j(x)=1.2x is only greater than the growth rate of h(x)=1.2x when its terms are greater.

The correct response 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.
This is because \( h(x) = 1.2x \) represents a linear growth, while \( j(x) = 1.2^x \) represents an exponential growth. Exponential growth ultimately increases more rapidly than linear growth, especially as x becomes larger.
