Help please!!

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

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

Answer 1

plug in the values of x and y into all these options

Answer 2

so how exactly would i put them in?

Answer 3

plug each set of points in

Answer 4

so plug them in one at a time like , 2=-2(-1)^2+2(-1); -58?

Answer 5

bingo

Answer 6

only one equation will satisfy all of them

Answer 7

okay , thank you :)
