Question

Compare the graphs of the inverse variations. y=1/x and y=2.5/x

Answer 1

The graph of

`y = (2.5)/(x)`

us a vertical stretch of the graph of

`y = (1)/(x)`

by a factor of 2.5.

Explanation:

The given functions are

`y = (1)/(x)`

and

`y = (2.5)/(x)`

The graph of

`y = (1)/(x)`

is the parent rational function.

The graph of

`y = (2.5)/(x)`

is a vertical stretch of the parent rational function by a factor of 2.5
