Answer:
Step-by-step explanation:
x - 3 -2 -1 0 1 2 3
y -9 -4 -1 0 - 1 -4 - 9
The trick here is to recognize what that minus sign in front of the x^2 does.
If it were not there, all of the y values would plus
y = x^2
y = (-3)^2
y = 9 For example.
Since the minus sign is in front of the x^2 value the answer is
y = - (-3)^2
y = - (9)
y = - 9
So all the values of y are all minus except 0 which has no sign.
