Att 6 a.m. the temperature was -5 degrees celscius. in the afternoon, the temperature was 10 degrees celscius. what was the change of temperature during the day?

D is correct

Step-by-step explanation:

We are given roots and leading coefficient of any polynomial.

Roots are -4,i and 2.

All are multiplicity 1.

One root is complex. As we know complex root in conjugate pair.

So, Conjugate of "i" is "-i"

Now, we have four roots with multiplicity 1

Required polynomial:

where, a is leading coefficient

So, a=3

Hence, The required polynomial function is
