The relation maps a unique output value to each input value. It is a function.
Answer:
is the required polynomial function of the form 
Step-by-step explanation:
The given zeroes of the polynomial is -5 and 4i.
It implies, the roots of the polynomial is (x+5) and (x-4i)
Now, The Polynomial = Product of all its roots
So, here P(x) = ( x + 5)( x - 4i)
or, 
⇒
Hence, P(x) is the required polynomial function of the form 
You're looking for the time

that it takes for the principal

to double, so

. Dividing both sides of the formula by

leaves you with

You're given that the account earns 0.75% interest and that the interest is compounded monthly, so

and

.
