Question

Which best describes the function on the graph?

O direct variation; k= 2
O direct vanation, k= 1/2
O inverse variation; k= 1/2
O inverse variation; k = 2

Answer 1

Answer: D

Step-by-step explanation: An inverse variation of two variable in which if one of the variable increases, then the other variable decreases at the same rate.

Answer 2

Answer: inverse variation; k = 2

Explanation:

y = k/x graph (inverse variation)

lets just plug 1 into x,

x = 1, y = k / 1 = k

in the graph. y = 2 when x = 1,

=> k = 2
