You can put this solution on YOUR website! Which point belongs to -y2 = x?
Is it:
a. ( 2,1)::::::-(1)^2 = 2::::: No
----------------------------------
b. ( 4,-2 ):::: -(-2)^2 = 4:::: No
---------------------------------
c. ( -4, -2)::: -(-2)^2 = -4::: Yes
-----------------------------------
d. ( 4, 2 ):::: -(2)^2 = 4::::: No
and what would be the solution?
y = -2 when x = -4
