The demand function for specialty steel products is given, where p is in dollars and q is the number of units. p = 165145 - q (a) Find the elasticity of demand as a function of the quantity demanded, q. n = Check which variable(s) should be in your answer. (b). Find the point at which the demand is of unitary elasticity. q Enter a number. Find intervals in which the demand is inelastic and in which it is elastic. (Enter your answers using interval notation.) inelastic elastic (c) Use information about elasticity in part (b) to decide where the revenue is increasing, and where it is decreasing. (Enter your answers using interval notation.) increasing decreasing Use information about elasticity in part (b) to decide where the revenue is maximized. 9 =
