B. Score(3)
C. Score + 3
D. 3 - score

Respuesta :

The correct answer is C

Answer:

B. Score(3)

Step-by-step explanation:

Given,

Bella's score on a spelling test is a function of the number of hours she studies.

Let x represents the number of hours and S represents her score after x hours,

Thus, her scoring after x hours = S( x )

If she studies for 3 hours,

That is, x = 3,

Then her score would be S(3) or we can say that score(3).

Hence, option 'B' is correct.
