Determine the domain of the function
To do this, we need to solve for the vertex, p of the function
Given the the general form of a quadratic function is:
By comparison, we have:
So:
Substitute 1 for p in
This implies that
The interpretation of this is that;
<em>For every value of p, there's a corresponding value of R.</em>
<em>However, because p indicates price and it's impossible to have a negative price, we can say that the minimum value of p is 0;</em>
Hence, the domain is
