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)

Write a polynomial function of least degree with integral coefficients that has the given zeros.

Triss [41]

Answer:

Step-by-step explanation:

To get the equation, you must create the factors containing the roots.

So for example the first set of roots can be produced from

(x -2)(x^2 + 9)

which equals (when expanded) x^3 + 9x - 2x^2 - 18 which when put in the correct order gives

x^3 -2x^2 + 9x - 18

The second one is a bit more difficult to judge.

-5 and -3+ square root(2)

I don't think this is a polynomial. The coefficent is not integral. (-3 +√2)
