See the 4-petal rose, in the Socratic graph. I have used the Cartesian equation, instead.

#### Explanation:

The period for the graph is

The size of each petal, in this 4-petal rose, is 4.

As

and so,

the span of

span of

In the other half of a period

Overall, for one round

the number of loops is

graph{1/4(x^2+y^2)^2.5-x^4+6x^2y^2-y^4=0 [-10, 10, -5, 5]}
