See graph and explanation.

#### Explanation:

The general equation to a cardioid having its dimple at r = 0 is

a gives the size and

Here, a = 1 and

The graph is symmetrical about

Now, see Socratic graph, depicting all these features.

I have used Cartesian form of the equation.

graph{x^2+y^2-sqrt(x^2+y^2)-y=0 [-5, 5, -2.5, 2.5]}
