You are multiplying the 3x by 6
the last choice is correct
Answer : (8,5)
Given
K(x) = ![8-\sqrt[3]{x}](https://tex.z-dn.net/?f=8-%5Csqrt%5B3%5D%7Bx%7D)
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
6:5. or 6/5 which ever way you choose
20,27,34
The common difference is 7
It would be 1n - 12 + 8y.
4n - 3n = 1n
12 + 8y don’t mix so we can leave it.
Therefore: 1n - 12 + 8y
