Solution

Step 1 :The question is asking us to predict the behavior of the function \(f(x)\) over certain intervals. We are given a table of values for \(f(x)\) at certain points. We need to check each of the given options against the values in the table to see which one is valid.

Step 2 :Let's define the function values as \(f(x)\) = {-3: -15, -2: -5, -1: 0, 0: 5, 1: 0, 2: -5}.

Step 3 :Let's define the options as {'\(f(x) \leq 0\) over the interval \((-\infty, \infty)\)': False, '\(f(x) > 0\) over the interval \((-1, \infty)\)': False, '\(f(x) \geq 0\) over the interval \([-1,1]\)': True, '\(f(x) < 0\) over the interval \((0,2)\)': False}.

Step 4 :From the above, we can see that the only valid option is '\(f(x) \geq 0\) over the interval \([-1,1]\)'.

Step 5 :Final Answer: The valid prediction about the continuous function \(f(x)\) is \(f(x) \geq 0\) over the interval \([-1,1]\). So, the final answer is \(\boxed{f(x) \geq 0 \text{ over the interval } [-1,1]}\).
