Final answer:
Kona's statement is correct; the maximum value of the function f(x) = -2^x is 0, which occurs when x equals 0.
Step-by-step explanation:
Kona's statement that the maximum value of f(x) = -2x is 0 is True. As x increases, the negative exponent results in smaller values of 2 to the power of x (2x), meaning f(x) will become more negative. However, when x is 0, f(0) = -20 equals -1 raised to the 0 power, which is 1. Then multiplying by the coefficient of -2 produces 0. Therefore, the maximum value that f(x) can achieve is when x equals 0 and f(x) is indeed 0.
