To compare the growth rates of the functions \( g(x) = 1.3^x \) and \( f(x) = 1.3x \), Austin should analyze the curves on a graph.
The correct statement is:
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 \( g(x) = 1.3^x \) to the right of their right-most intersection point.
Explanation:
- Growth Rates: \( g(x) = 1.3^x \) is an exponential function, which generally increases faster than \( f(x) = 1.3x \), a linear function, as \( x \) becomes large.
- Intersections: At some points, particularly at small values of \( x \), \( f(x) \) may be greater than \( g(x) \). However, beyond a certain point, \( g(x) \) will exceed \( f(x) \) and continue to grow at a faster rate.
- Conclusion: Thus, the intersection point indicates where the growth rates will change in relation to each other. Beyond this point, \( g(x) \) will be greater than \( f(x) \).
