Question

Find a quadratic function to model the values in the table. Predict the value of y for x = 6.
x y
1 2
0 2
3 -10

Answer 1

A. y=-2x^2+2x-2; -58
B. y=2x^2-2x-2; 60
C. y=2x2-2x-2; 58
D. y=-2x2+2; -58

Answer 2

those values don't fit any of the above

eg x = 0, y =2 fits D but x = 1 y =2 does not
x=0, y=2 does not fit A,B or C
