Thet contradict each other, that's why both of them are incorrect.
<span>Suppose that a polynomial has four roots: s, t, u, and v. If the polynomial were evaluated at any of these values, it would have to be zero. Therefore, the polynomial can be written in this form.
p(x)(x - s)(x - t)(x - u)(x - v), where p(x) is some non-zero polynomial
This polynomial has a degree of at least 4. It therefore cannot be cubic.
Now prove Kelsey correct. We have already proved that there can be no more than three roots. To prove that a cubic polynomial with three roots is possible, all we have to do is offer a single example of that. This one will do.
(x - 1)(x - 2)(x - 3)
This is a cubic polynomial with three roots, and four or more roots are not possible for a cubic polynomial. Kelsey is correct.
Incidentally, if this is a roller coaster we are discussing, then a cubic polynomial is not such a good idea, either for a vertical curve or a horizontal curve. I hope this helps</span><span>

Find the b value by plugging in the slope and known coordinates,
-2=0(4)+b
-2= 0+b
-2=b
You can also tell this without calculating since a slope of 0 will always have the same y value. Therefore if (4,-2) is on the line, the y value of the whole line must be -2.
Final answer: y=0x-2, which is y=-2
Answer:
a) Data degradation
Step-by-step explanation:
These are the options for the question.
a) Data degradation
b) Data rot
c) Data security
d) Scattered data
From the question, we are informed about how difficult it's to manage data. For example, it is common for customers to move and for companies to go out of business. This case is an example of Data degradation. Data degradation can be regarded as
corruption of computer data, or gradual alterations of data, and this could be as a result of accumulation of failures in storage devices that store the data, this failure can be critical one or non-critical one
