For this case we have a function of the form:
y = f (x)
Where,
x: independent variable
y: dependent variable
To answer the question, we must see in the table the values of the independent variable x, for which the values of the dependent variable f (x) are negative.
We have then that the interval that fulfills this condition is from minus infinity to minus 4 without including the 4.
Thus,
(–∞, –4)
Answer:
The entire interval over which the function, f(x), is negative is:
D) (–∞, –4)
Answer:
Explanation:
Binomial expansion is:

Here in given expression we have a=x , b=-2y and n = 13
general formula for binomial expansion is:

Since, 
r should be one number less than the term we need to find so it will become the number we need to find like here we have to find 9th term so, r=8
substituting the values in the genral formula we will get

After substituting the values we will get

After simplification we will get
which will be the 9th term of the expansion
<span>Number line refers to a mathematical process of
solving the equation with the use of lines.
=> 235 + 123
Starting from 0 you count 1 up to 235. Then starting from 235 you additionally
count another 123.
Then from zero start counting the total number to the line you stopped when
adding 123 to 235.
This simply equals to
=> 235 + 123
=> 358.

Answer:
Slope = rise / run
= -12 / 1500 (It's -12 and not 12 because a drop means it's decreasing)
= -0.008
