Which of the following equations is an example of inverse variation between the variables x and y?
y = x/3, y = 3/x, y = x + 3, y = 3x

Solution:

We know that, 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

So,

We know that the following function is an inverse variation:

y = 3/x

Therefore, the equation which is an example of inverse variation is y = 3/x.

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

Summary:

The equation is an example of inverse variation between the variables x and y is y = 3/x.
