Question

Please help me on this problem.

Answer 1

Answer : (8,5)

Given

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

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

(-64,12)

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

(125,3)

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

(343,1)

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

(8,5)

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