Question

(Need help please and thank you!) :)

Answer 1

Explanation:

In order to find the f(x) or y value, you have to replace x with the given one in the table:

x = -1,

`y = \sqrt[3]{ - 1 - 7} = \sqrt[3]{ - 8} = - 2`

.

x = 6,

`y = \sqrt[3]{ 6 - 7} = \sqrt[3]{ - 1} = - 1`

.

x = 7,

`y = \sqrt[3]{7 - 7} = \sqrt[3]{0} = 0`

.

x = 8,

`y = \sqrt[3]{8 - 7} = \sqrt[3]{1} = 1`

.

x = 15,

`y = \sqrt[3]{15 - 7} = \sqrt[3]{8} = 2`

Also, the correct graph is in the 2nd photo, where the root is (7; 0)
