Find the third degree polynomial function that has an output of 40 when x=1, and has zeros −19 and −i?

Step-by-step explanation:

Complex numbers:

The following relation is important for complex numbers:

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.

Has zeros −19 and −i

If -i is a zero, its conjugate i is also a zero. So

Output of 40 when x=1

This means that when . We use this to find the leading coefficient a. So

The polynomial is:

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
