Answer : (8,5)
Given
K(x) =
Now we plug in each point and check whether it satisfies our equation
(-64,12)
K(-64) = = 12 so this point lie on graph
(125,3)
K(125) = = 3 so this point lie on graph
(343,1)
K(343) = = 1 so this point lie on graph
(8,5)
K(8) = = 6 so this point does not lie on graph because we got 6 instead of 5
