question 17 options: 63 /55 295 /49 384/ 7 -57/ 7

63/55

Step-by-step explanation:

Assuming and . Find  ( g o f)(­ -7) by substituting f into g. Then -7 into the new expression.

( g o f)(­ -7) =

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
