Question

I need help answering this question it is 3 parts

Answer 1

Given the following function:

$\text{ y = -}\frac{2}{7}\text{x}^7$

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,

$\text{ y = -}\frac{2}{7}(-1)^7\text{ = -}\frac{2}{7}(-1)\text{ = }\frac{2}{7}$

Point 1 : (-1, 2/7)

At x = 0,

$\text{ y = -}\frac{2}{7}(0)^7\text{ = 0}$

Point 2: (0, 0)

At x = 1,

$\text{ y = -}\frac{2}{7}(1)^7\text{ = -}\frac{2}{7}(1)\text{ = -}\frac{2}{7}$

Point 3: (1, -2/7)

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

Therefore, the answer is CHOICE B.
