Question

The number of camera phones shipped globally can be modeled by the function y=1.28e^1.31x where x is the number of years since 1997 and years since 1997 and y is the number of camera phones shipped in millions. how many camera phones were shipped in 2014

Answer 1

Actually, for the answer above mine, it is actually 18 years apart from each other since you forgot to count the year 2000. So the answer is 22277879622.535936

Explanation:

Here is why! Same formula since it was correct but count the years

1. 1997

2. 1998

3. 1999

4. 2000

5. 2001

6. 2002

7. 2003

8. 2004

9. 2005

10. 2006

11. 2007

12. 2008

13. 2009

14. 2010

15. 2011

16. 2012

17. 2013

18. 2014

y=1.28 * e^(1.31 (18))

y=22277879622.535936

Answer 2

The first thing you should know for this case is how many years there are from 1997 to 2014.
The number of years is:
x = 2014-1997 = 17
Then, you must replace this value in the given equation:
y = 1.28e ^ 1.31x
y = 1.28 * e ^ (1.31 * (17))
y = 6011018736
answer:
the number of camera phones shipped in millions in 2014 is
y = 6011018736
