Question

OBO QBODO 100

Which best describes the function on the graph?
direct variation; k = 1
direct variation; k = 4
inverse variation; k=1
inverse variation; k= 4

Answer 1

inverse variation; k=4

Explanation:

took the test on edge2020 :)

Answer 2

Inverse variation k=4

Explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
`y*x=k` or
`y=k/x`

In this problem

The graph represent a inverse variation

Because

if x increases ----> y decreases

if x decreases ----> y increases

Find the value of k

we have that

For x=2, y=2 -----> see the graph

`k=y*x`

substitute

`k=2*2=4`
