Answer:
Mr. Edelstein drove 48 miles per hour.
Step-by-step explanation:
12 miles for every 15 minutes
There are 60 minutes in an hour
Divide 60 by 15= 4
So you would multiply 12 by 4= 48
(x² +9) and g(x) are factors of f(x).
That is, (x² +9)(g(x)) = f(x).
The roots of (x² +9) are roots of f(x). They are 3i and -3i.
The factor (x² +9) has degree 2, so f(x) has degree at least 2.
We cannot say anything about the x- or y-intercepts based on this information.
Imaginary roots usually come in even numbers (2, 4, etc.) for the polynomials we study. The information given here does not support the idea of 3 imaginary roots for f(x).

Let d=discriminant. The the rule is:
d>0, there are two real solutions
d=0, there is one real solution
d<0, there is no real solutions (but there are two imaginary solutions)
So if it is positive, there are two real solutions.
