Answer:
Approximately 80,083 dolls were sold in year 1994.
Step-by-step explanation:
We are given the following information in the question:
The function f(x) estimates the number of dolls that were sold in thousands during a given year from 1993 to 2003.
[tex]f(x) = -0.022x^4 + 0.457x^3 -2.492x^2-5.279x+87.419[/tex]
where x is the number of years since 1993.
We have to estimate the number of dolls that were sold in 1994.
We put x = 1, as x x is the number of years since 1993. Thus, it is 1 year for 1994 since 1993
Putting values, we get,
[tex]f(1) = -0.022(1)^4 + 0.457(1)^3 -2.492(1)^2-5.279(1)+87.419 = 80.083 [/tex]
Thus, approximately 80,083 dolls were sold in year 1994.
