Given the following price-demand function, find the elasticity of demand, E(p),

Given the following price-demand function, find the elasticity of demand, E(p), and determine whether demand is elastic, inelastic, or has unit elasticity for the following values of p. (Round your answers to two decimal places.)
x = 303,750 − 50p2
(a)p = 34
E(p) =
(b)p = 60
E(p) =
(c)p = 50
E(p) =
And say wether it is elastic, inelastic, or has unit elasticity for the following values of p
