D. (5,2)
when i plug it in it seems wrong..

Answer 1

would it be B ? or no

Answer 2

it's b

Answer 3

When you plug in (2,-2), you're plugging in x=2 and y = -2 to get


-6x^2+20x-17 > y


-6(2)^2+20(2)-17 > -2


-6(4)+20(2)-17 > -2


-24+40-17 > -2


-1 > -2


which is true


So you are correct.

Answer 4
