Answer:
ANSWER:
= The value of x is changing with a constant difference of 1.
= The difference in y value are:
= -4, -2, 0, 2, 4
= 2, 2, 2, 2
= quadratic function for given data is
f(x) ax² + bx + c
= (-2) = a (0) + b(1) - c
= c = -2
again, (0) = a(2)² + b(2) - 2
4a + 2b = 2
= 2a + b = 1 = 11
from 1 & 2, b = -1, a = 1
hence the eqn is
= x² - x - 2 = 0
