Answer:
The range is:
{-4, 1, 2, 5, 8}
Step-by-step explanation:
Given the function
- We know that the domain of a function is the set of input or argument values for which the function is real and defined.
As the domain interval -2 ≤ x ≤ 2
i.e. the values in the domain = {-2, -1, 0, 1, 2}
- We also know that the range of a function is the set of values of the dependent variable for which a function is defined.
As the domain interval -2 ≤ x ≤ 2
Putting all the x-values in the domain interval in the function
so
putting x=-2 in the function
putting x=-1 in the function
putting x=0 in the function
putting x=1 in the function
putting x=2 in the function
Thus, when we put the domain values, the corresponding range values are:
x y
-2 -4
-1 1
0 2
1 5
2 8
Therefore, the range is:
{-4, 1, 2, 5, 8}

Step-by-step explanation:
Answer:
- Scale Factor from the image to the actual= 765
- y=765x
Step-by-step explanation:
The scale of the flag from the image to the actual were 1 inch = 63.75 ft.
Now, 1 foot = 12 inches
63.75 feet = k inches
k= 63.75 X 12 =765 inches
Therefore: 1 Inch represents 765 Inches
Scale Factor from the image to the actual= 765
If y is the length of the actual and x is the length of the image, then:
y=765x
Answer:
the critical value for 0.87 level of confidence is 1.51
Step-by-step explanation:
Given the data in the question;
level of confidence = 0.87
now,
1 - c = 0.87
c = 1 - 0.87
c = 0.13
c/2 = 0.13/2 = 0.065
now
1 - c/2 = 1 - 0.065 = 0.935
so our level of significance ∝ = 0.935
Now, the critical value will be;
is obtained as follows;
P( Z < z ) = 0.935
so we find the value from ( standard normal distribution table )
P( Z < 1.51 ) = 0.935
Therefore, the critical value for 0.87 level of confidence is 1.51
