The prefix means 8.How to remember this is a octagon which has 8 sides.Therefore Octa means eight.I hope this helped.
Answer:

Step-by-step explanation:
If a real number
is a zero of polynomial function, then

is the factor of this function.
If a complex number
is a xero of the polynomial function, then the complex number
is also a zero of this function and

are two factors of this function.
So, the function of least degree is

If the polynomial function must be with integer coefficients, then it has a form

4.50 and 8 I think the answer is
Linear mathematical models describe real world applications with the use lines. For instance, a car going 50 mph, has traveled a distance represented by y=50x, where x is time in hours and y is miles. The equation and graph can be used to make predictions.
