Find a polynomial function of degree 7 with -2 as a zero of multiplicity​ 3, 0 as a zero of multiplicity3 ​, and 2 as a zero of multiplicity 1.

The polynomial is , in which a is the leading coefficient.

Step-by-step explanation:

Zeros of a function:

Given a polynomial f(x), this polynomial has roots such that it can be written as: , in which a is the leading coefficient.

-2 as a zero of multiplicity​ 3

This means that:

0 as a zero of multiplicity 3  

Then also:

2 as a zero of multiplicity 1.

Then:

Adding the leading coefficient:

The polynomial is , in which a is the leading coefficient.

80

step-by-step explanation:

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
