To determine which statement is true, we need to evaluate f(7) and g(7) and compare the results.
First, let's evaluate f(7):
f(x) = 4x^5
f(7) = 4(7)^5 = 4(16807) = 67228
Next, let's evaluate g(7):
g(x) = 7.3^x
g(7) = 7.3^7 = 7(2187) = 15309
Comparing the two values, we can see that f(7) is greater than g(7).
Therefore, the correct statement is: f(7) > g(7).
