Answer:
y = -2(x -2)^2 + 11
Step-by-step explanation:
It works well to factor the leading coefficient from the first two terms.
... y = -2(x^2 -4x) +3
Now we want to add the square of half the x-coefficient inside parentheses, and subtract the equivalent quantity outside parentheses.
... y = -2(x^2 -4x +4) +3 - (-2·4)
... y = -2(x -2)^2 +11 . . . . . . . . simplify
_____
The form given in the problem statement is called "vertex form," where the vertex of the parabola is (h, k). A graph shows us the vertex is (2, 11), so we can write the function immediately as ...
... y = -2(x -2)^2 +11

Answer:
C. 7 - 3 = 4
Step-by-step explanation:
Given
Required
The IQR
The IQR is calculated using:
Where:
Median of the upper
Median of the lower
The dataset has 7 values, so the median is: (7 + 1)/2 =8/2 = 4th position.
Split to two, we have:
The lower half has 3 data; So, the median is the 2nd position.
Hence:
The upper half has 3 data; So, the median is the 2nd position.
Hence:
So, the IQR is:
