15. When written in standard form, which polynomial has a leading coefficient of \( 5 \) ?
F \( - 7 + 6 y + 5 y ^ { 2 } \)
G \( x + 5 \)
H \( x ^ { 2 } - 5 x ^ { 3 } + 2 x \)
J \( 5 y + 3 y ^ { 2 } - 4 \)
16. Classify the polynomial \( 3 x ^ { 5 } + 3 \) according to its degree and number of terms.
A cubic binomial
B cubic trinomial
C quintic binomial
D quintic trinomial
15.) option F is correct
16.) option C is correct
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.
