E(p) = uv dp dD p dp D D. E(p) = lim US dp² AD→0 ` = f''(p), where |v| = |f'(p)| and v= = f(p) where D = f(p+AD)-f(p) AD = f'(p), where D = р P-30 The demand is said to be elastic when The demand is said to be inelastic when = f(p) <E< <E< US -= f'(p) dp The price elasticity of demand is E(p) = (Type an expression using p as the variable.) d. For what prices is the demand elastic? Inelastic? Identify the values of E for which the demand is said to be elastic and the values of E for which the demand is said to be inelastic. 1900 P-30 where D(p) is the number of tires of one brand and size that can be
