Question 622103
Plug in x = 1 (basically any x value you want) and follow the same method shown before


y=-2x^2+3 


y=-2(1)^2+3 


y=-2(1)+3


y=-2+3


y=1


So another point is (1,1)


By symmetry, another point is (-1,1) since x = -1 and x = 1 are both one unit away from the line of symmetry x = 0.
