Question

the number of web searches S in billions on a particular web during year x can be approximated by S(x)=227x-454,921 from 2009 to 2012. Evaluate S(2011) and interpret the result.​

Answer 1

1576 Billions.

That means in the year 2011, the number of web searches on that particular web can be approximated as 1576 billions.

Explanation:

The number of web searches S(x) in billions on a particular web during year x can be approximated by

S(x) = 227x - 454,921 ....... (1) from 2009 to 2012

Therefore, S(2011) = 227 × 2011 - 454921 = 456497 - 454921 = 1576 Billions.

That means in the year 2011, the number of web searches on that particular web can be approximated as 1576 billion. (Answer)
