Answer:
B. y = (x + 3)^2 - 17
Step-by-step explanation:
When Andy completes the square, he adds and subtracts the square of half the x-coefficient. That is, he adds and subtracts (6/2)² = 9:
... y = x² +6x +9 -8 -9
... y = (x² +6x +9) -17
... y = (x +3)² -17 . . . . . . . . matches selection B
The range is the difference betweem the largest and smallest NUMBERS in the whole piece of data. The IQR is the difference between the largest and smallest QUARTILES. For example, if you had the data 1,2,3,4,5: 5-1=4 would be the range and...(4-2)=2 would be the IQR. Hope this helped! :)
