This equation is an example of a Limacon with inner loop. By using the symmetry tests where:
POLAR AXIS/HORIZONTAL:
replace a) θ by -θ, b) r by -r and θ by π-<span>θ
VERTICAL AXIS:
replace a) </span>θ by π-θ, b) r by -r and θ by -<span>θ
POLE:
replace a) </span>θ by π+<span>θ, b) r by -r
If any of these rules, after replacing it in the equation, results to the original equation (making it the equivalent) then it is symmetrical to that axis.
In this case, it is only symmetrical about the polar/horizontal axis. </span>

Answer: a)
, b)
c) $5761.36.
Step-by-step explanation:
Since we have given that
Unit price is expressed as

Let x be the number of units of a thousands.
So, Revenue function is given by

.(b) Find the marginal revenue function R'..
Marginal revenue function becomes,

(c) Compute R'(2).

Hence, a)
, b)
c) $5761.36.
