The demand function for specialty steel products is given, where p is in dollars and q is the number of units. p = = 90/145-9 (a) Find the elasticity of demand as a function of the quantity demanded, q. 3(-9+145) 77 = 9 (b) Find the point at which the demand is of unitary elasticity. g=108.75 Find intervals in which the demand is inelastic and in which it is elastic. (Enter your answers using interval notation.) inelastic elastic (108.75,00) x (-00,108.75) x (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 (0,90) decreasing (90,00) x Use information about elasticity in part (b) to decide where the revenue is maximized. 9 = 108.75
