Question

Study the table. Which best describes the function represented by the data in the table? X= -2,-1,0,1,2 Y= 8,2,0,2,8

Answer 1

Its a quadratic function y = 2x^2.

Explanation:

8 = 2(-2)^2

2 = 2(-1)^2

0 = 2(0)^2

2 = 2(1)^2

8 = 2(2)^2

So the function is y = 2x^2 ( a quadratic function)
