Answer
The function \( P = 2(1.45)^x \) models **exponential growth**, has an initial amount of **2**, and a growth rate of **45%**. Therefore, statements A, D, and F are true.

This function indeed models exponential growth as indicated by the base of the exponent, which is greater than 1! In this case, as \( x \) increases, \( P \) will grow rapidly. So, it's safe to say statement A is correct! Now, onto the initial amount—when \( x = 0 \), the function evaluates to \( P = 2(1.45)^{0} = 2(1) = 2 \). So, statement D holds true as well. Let's fill those boxes! 🚀
