By graphing the given equation
r = 4 - 3 sin θ
We find that the graph is symmetric about the y-axis
The graph of the given equation is attached below

Some information about the given equation:
the given equation is like the form of the Cardioid
A curve that is somewhat heart shaped. A cardioid can
be drawn by tracing the path of a point on
a circle as the circle
rolls around a fixed circle of the
same radius.
The equation is usually written in polar
coordinates.
Equations of Cardioid:
r = a ± a cos θ (horizontal)
or r = a ± a sin θ (vertical)
