Answer: The value of f(3) is 9 and the correct option is 4th.
Explanation:
In the given table first column represents the value of x and the second column represents the value of f(x).
In first row x = -3 and f(x) = -9, it means the value of the function is -9 at x = -3. It can be written as f(-3) = -9.
Similarly in second row x = -2 and f(x) = -6, it means the value of the function is -6 at x = -2. It can be written as f(-2) = -6.
Since we have to find the value of f(3), it means we have to find the value f(x) at x=3.
From the last row of the table we noticed that f(x)=9 at x=3. The value of the function is 9 at x=3. It can be written as f(3)=9.
Therefore, the value of f(3) is 9 and the correct option is 4th.
