Question

I need help answering this question it is 3 parts

Answer 1

Given the following function:

`\text{ y = -}(2)/(7)\text{x}^7`

Let's determine which graph correctly represents the given equation by determining its approximate coordinates.

Let's determine at x = -1, 0 and 1.

At x = -1,

`\text{ y = -}(2)/(7)(-1)^7\text{ = -}(2)/(7)(-1)\text{ = }(2)/(7)`

Point 1 : (-1, 2/7)

At x = 0,

`\text{ y = -}(2)/(7)(0)^7\text{ = 0}`

Point 2: (0, 0)

At x = 1,

`\text{ y = -}(2)/(7)(1)^7\text{ = -}(2)/(7)(1)\text{ = -}(2)/(7)`

Point 3: (1, -2/7)

Among the graph, the one that best represents the equation is:

Therefore, the answer is CHOICE B.
