You are given a pair of equations, one representing a supply curve and the other representing a demand curve, where p is the unit price for x items.
-45 x^2 - 74.5199999999995 x + 15921.36 - 1224.72 p = 0
and
54 x^2 + 1743.12 x + 13880.16 - 6940.08 p = 0
a. Identify which is the supply curve and demand curve and the appropriate domain. Put the domains in interval notation . For \infty type infinity . For more than one interval use a U to represent a union .
Domain of the supply curve
Domain of the demand curve
b. Determine the market equilibrium. Equilibrium: x = p =
c. Determine the revenue function. Revenue function R(x)=
d. Determine the revenue at market equilibrium.
I don't know how to solve it for x^2...
