Answer:
the domain is that x is a set of real numbers.
the range is y ≤ -3
Step-by-step explanation:
y = -|x + 3|
y is either positive or equal to zero.
Now, x is all real numbers because any value of x used will yield a valid value of y.
Thus, we can say that the domain is that x is a set of real numbers.
Now, for the range:
The minus sign in front of the absolute value indicates that the function has a maximum value.
Thus, the range is y ≤ -3
The third one :) I hope I did it right
Variable A - horizontal axis ⇒ x
Variable B - vertical axis ⇒ y
points (x, y)
A B
1) 2 , 2
2) 2 , 8
3) 4 , 3
4) 5 , 1
5) 6 , 3
6) 7 , 5
7) 8 , 6
8) 9 , 2
Mean of Variable A.
(2 + 2 + 4 + 5 + 6 + 7 + 8 + 9) ÷ 8 = 43 ÷ 8 = 5.375 OR 5.40
Mean is the average value of the data set. Add all the numbers in the data set and divide its sum by its count.
10√2 is the answer for square root of 200
