Final answer:
The graph of the function f(x) is less than 0 over the interval (-2,-3) and the interval (-2.4, -1).
Step-by-step explanation:
In order to analyze the graph of the function f(x) over the interval (-2,-3), we need to find the values of x for which f(x) is less than 0. The given interval (-2, -3) includes the values of x between -2 and -3, exclusive. From the graph, it can be observed that f(x) is also less than 0 over the interval (-2.4, -1).
Therefore, the correct answer is option C. (-2.4, -1).
