Answer:
Step-by-step explanation:
To find the real zeros you must match the function to zero and factor the expression.
We have a polynomial of degree 3.
We try to group the terms to perform the factorization
Now we take (x + 4) as a common factor
If we have an expression of the form 
we know that this expression is equivalent to:
In this case
So:
Finally:
The solutions are:
An outlier causes the range of the population to move slightly towards the outlier.
Answer:
Direct Variation. Since k is constant we can find k when given any point by dividing the y-coordinate by the x-coordinate.
For this there is no exact square root but the closest it get is about 75.33
Y=x-4
From this we plug in the answer to find the y value!
For example y=3-4=-1 A.) would be incorrect!
Y=3-4=-1 B.) would be incorrect!
C.) y= -3-4=-7 while it’s SUPPOSE to be 7.
D.) y= -3-4=-7 and y value is -7
Correct answer: D!
