The answer is "Option C".
Step-by-step explanation:
In the given question attachment of the table is missing which can be defined as follows:
In given table a method f(x) values corresponding to different values of x. Â
We needed to try f(0) value  that is in this method, we have to calculate the f(x) value if x=0 Â
As we've seen from the table the f(x) value at x=0 is 6 Â
That's why the correct choice is option C that is 6.
