Answer : (8,5)

Given

K(x) = [tex]8-\sqrt[3]{x}[/tex]

Now we plug in each point and check whether it satisfies our equation

(-64,12)

K(-64) = [tex]8-\sqrt[3]{-64}[/tex]= 12 so this point lie on graph

(125,3)

K(125) = [tex]8-\sqrt[3]{125}[/tex]= 3 so this point lie on graph

(343,1)

K(343) = [tex]8-\sqrt[3]{343}[/tex]= 1 so this point lie on graph

(8,5)

K(8) = [tex]8-\sqrt[3]{8}[/tex]= 6 so this point does not lie on graph because we got 6 instead of 5
