A coordinate plane shows an increasing solid curve and a dotted straight line plotted on it, each representing a function.
Olive is comparing the growth rates of p(x)=5x
and q(x)=20x
using this graph. Based on the graph, Olive concludes that the growth rate of q(x)=20x
is always greater than the growth rate of p(x)=5x
. Where is her mistake?

Olive has it backward. The growth rate of p(x)=5x
is always greater than the growth rate of q(x)=20x
.
Olive has it backward. The growth rate of p left parenthesis x right parenthesis equals 5 superscript x baseline is always greater than the growth rate of q left parenthesis x right parenthesis equals 20 x .
Olive is only considering a small portion of the domains of the functions. If she went farther to the left on the graph, she would observe that the growth rate of p(x)=5x
eventually surpasses the growth rate of q(x)=20x
for large negative values of x
.

The growth rate of q(x)=20x
is only greater than the growth rate of p(x)=5x
when x
is greater than approximately 0.
