Question

which of the following equations is an example of inverse variation between the variables x and y?

A. y=x/3
B. y=3/x
C. y= x+3
D. y= 3x

Answer 1

 An inverse variation by definition is given by a function of the form:
 $y = k / x$
 Where,
 k: is a constant that can be any real number.
 x: represents the independent variable
 y: represents the dependent variable
 We have then that the following function is a reverse variation:
 $y = 3 / x$
 Answer:
 B. y = 3/x

Answer 2

Answer:    B. y=3/x

Step-by-step explanation:

For any variable x and y the inverse relationship is given by :-

$y=\frac{k}{x}$, where k is the inverse proportionality constant.

From the given options option B is  showing  inverse variation between the variables x and y.

tex]y=\frac{3}{y}[/tex], where 3 is the inverse proportionality constant.
