ANSWER
B. The graph is symmetric about the origin
EXPLANATION.
The given function is
When a=1,
Let,
Since n is odd,
This implies that, the function
is symmetric with respect to origin.
The correct answer is B
Answer:
y (x² + 1) (x² - 5)
Step-by-step explanation:
<h3>Factorization:</h3>
Take 'y' from each term.
x⁴y - 4x²y - 5y = y[x⁴ - 4x² - 5]
Now factorize x⁴ - 4x² - 5.
Sum = -4
Product = -5
Factors = -5 , 1
When we add (-5) + 1, it gives (-4) and when we multiply (-5)*1, gives (-5).
x⁴ - 4x² - 5 = x⁴ + x² - 5x² - 5
= x²(x² + 1) -5(x² + 1)
= (x²+ 1) (x² - 5)
x⁴y - 4x²y - 5y = y (x² + 1) (x² - 5)
A self-selecting sample is not likely to be representative. The reason why a self-selecting sample is not likely representative would be discussed below.
<h3>What is self-selecting sample?</h3>
A self-selection sample is determined by the individual that are used as data for the research. They are the ones that will determine the inclusion or exclusion of the sample units by either affirming or declining to participate.
The reason self-selecting sample is not likely to be representative is that it is too bias as the individuals that volunteered may not be able to satisfy the goals of the research.
Therefore, a self-selecting sample is not likely to be representative.

Quadratic equation is the correct answer since there are 2 x-terms which is the first where ax^2 and then bx which leaves a constant.
It is a because the model is up then b so it will be a
