Question

30. The table above gives values of the quadratic function f for selected values of x. Which of the following defines f ?
(A) f(x)= x2 +1 (B)f(x)= x2 +2 (C)f(x)=2x2 -2 (D) f(x)=2x2 -1 (E)f(x)=2x2 +1

Answer 1

look at question 30

Answer 2

since \(f(0)=1\) you can rule out everything but A and E

Answer 3

A. f (x) = x^2 + 1

Answer 4

then check a couple other numbers and see what works
