Y= 3( x -2 )² - ( x-5 )² = 3 ( x² - 4 x + 4 ) - ( x² - 10 x + 25 ) =
= 3 x² - 12 x + 12 - x² + 10 x - 25=
= 2 x² - 2 x - 13 =
= 2 ( x² - x + 1/4 - 1/4 ) - 13 =
= 2 ( x - 1/2 )² - 1/2 - 26/2 = 2 ( x - 1/2 )² - 27/2
Answer: D)

m = {-13, -1}</span>
1,200,354,226,320 divided by 666,222,346 is 1801.73216
8-4=4
9-6=3
Use Pythagorean theorem.
The nearest tenth is 5.
So the answer is point D.)
Mode 17,
Mean is 19.3
