(1 point) Dolores bought a box of \( 200 \) plastic garbage bags. She uses an average of \( 4 \) bags a week. (a) Write an equation relating the number of bags left after \( w \) weeks:
\( B ( w ) = \square \)
(b) Determine how many bags are left after \( 15 \) weeks. \(\square\)
\(B ( w ) = 200 - 4 w\)
\(140\)
Find the inverse for each of the following functions.
\(f ( x ) = 3 x + 1\)
\(g ( x ) = 1 x ^ { 3 } - 5\)
\(h ( x ) = \frac { 3 } { x + 5 }\)
\(j ( x ) = \sqrt[ 3 ] { x + 1 }\)
The total revenue from the sale of a popular book is approximated by the rational function \( R ( x ) = \frac { 1700 x ^ { 2 } } { x ^ { 2 } + 4 } \) , where \( x \) is the number of years since publication and \( R ( x ) \)
is the total revenue in millions of dollars.
(a) Find the total revenue at the end of the first year.
(b) Find the total revenue at the end of the second year.
