Austin is using graphs to compare the growth rates of g(x)=1.3x

and f(x)=1.3x
. Which statement correctly describes how Austin should do this and what he will observe? (1 point)
Responses

Austin should compare the steepness of the curves. The growth rate of f(x)=1.3x
will quickly surpass the growth rate of g(x)=1.3x
.
Austin should compare the steepness of the curves. The growth rate of f left parenthesis x right parenthesis equals 1.3 superscript x baseline will quickly surpass the growth rate of g left parenthesis x right parenthesis equals 1.3 x .

Austin should find where one curve is above the other curve on the graph. The growth rate of g(x)=1.3x
is greater than the growth rate of f(x)=1.3x
between the intersection points of the curve.

Austin should find where one curve is above the other curve on the graph. The growth rate of f(x)=1.3x
is only greater than the growth rate of g(x)=1.3x
to the right of their right-most intersection point.

The correct statement that describes how Austin should compare the graphs and what he will observe is:

Austin should compare the steepness of the curves. The growth rate of f(x)=1.3^x will quickly surpass the growth rate of g(x)=1.3x.

This is because \( f(x) = 1.3^x \) is an exponential function, which grows much faster than the linear function \( g(x) = 1.3x \) as \( x \) increases. Hence, the steepness of the curve for the exponential function will exceed that of the linear function at a certain point, demonstrating that the growth rate of \( f(x) \) surpasses that of \( g(x) \).
