A once-popular children's doll is slowly declining in popularity. the quartic function f (x)equals negative 0.022 x superscript 4 baseline plus 0.457 x cubed minus 2.492 x squared minus 5.279 x plus 87.419 commaf(x)=−0.022x4+0.457x3−2.492x2− 5.279x+87.419, where x is the number of years since 1993, can be used to estimate the number of dolls of this type that were sold (in thousands) during a given year from 1993 to 2003. estimate how many dolls were sold in 19941994.

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.

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,

Thus, approximately 80,083 dolls were sold in year 1994.
