Answer:
A. 0 because 5 is the minimum
Step-by-step explanation:
Use the formula
x = − b
/2
a
to find the maximum and minimum.
(
0
,
5
)
Multiple x² by -1 would flip it across x-axis so -x² would have maximum value 0. Now multiplying -x² by 2 stretch it vertically, however 2 times 0 is still 0 so maximum value is still 0. Now we add it by 5 which makes it shifts 5 units up, so this affects maximum value. So everything will be shifted 5 units up, so new maximum would be 5. Final 5
