Here, you have to determine values of f(x) for negative domain. Domain are those values of x for which function is defined.
Since the function is a polynomial, every value of x∈R is defined for f(x).
And for every negative value of x, f(x) will always be positive because x is squared and square of negative real number is always positive.
0 is neither negative nor positive. Therefore, zero is not included in negative domain. If you plug say x= -0.00000956, f(x) will be greater than 1 because square of x will never be negative.
Thus, the range will always be positive or greater than equal to 1.
Therefore, y≥1
Answer:
The probability that all nine references are still good two years later is P(all nine are still good)=0.29.
The assumption we have to make is that the occurrence of the site references in the paper are independent events.
Step-by-step explanation:
The assumptions we have to make about the papers is that their probabilities of survival are independent of each other. This is the same as saying: The occurrence of the site references in the paper are independent events.
The probabilities of survival of any reference is:

The probability of the nine references are still good later can be calculated as:

The probability that all nine references are still good two years later is P=0.29.
Correct answer should be= 1.5 hours is 75% of 6.
Answer:
-1/2
Step-by-step explanation:
Slope from equation,
y-3= -1/2(x-2)
y-3=-x/2+1
2y-6=-x+2
x+2y=8
m=-coefficient of x/coefficient of y =-1/2=-1/2
Slope from graph,
(2,3), (4,2) as (x1,y1) , (x2,y2)
m=(y2-y1)/(x2-x1)=(2-3)/(4-2)=-1/2
