Values of y are -8, -3, 0, 1, 0, -3, -8.

Work Step by Step

x can take values from -3 to +3, i.e. -3,-2,-1,0,1,2,3. We need to find value of y for above values of x. Therefore, For $x=-3, y=1-(-3)^{2}=1-9=-8,$ For $x=-2, y=1-(-2)^{2}=1-4=-3,$ For $x=-1, y=1-(-1)^{2}=1-1=\,\,0,$ For $x=\,\,\,\,0, y=1-(0)^{2}=1-0=1,$ For $x=1, y=1-(1)^{2}=1-1=0,$ For $x=2, y=1-(2)^{2}=1-4=-3,$ For $x=3, y=1-(3)^{2}=1-9=-8,$
