Since, the function F(x) represents the monthly earnings of sales executive, which consists of a base salary and a commission earned on each scale, where 'x' is the number of sales.
So, the function F(x) can be expressed as:
F(x)= base salary+ commission earned on each sale (x) where 'x' represents the number of sales done.
So, F(0)= base salary + 0 ( As x=0 implies there was no sale)
And the executive earned only his base salary and no commission as he did not make any sale, and the commission was dependent upon the number of sales (x).
Hence, F(0) represents the base salary.
So, Option J is the correct answer.
