If a price-demand equation is solved for p, then price is expressed as p=g(x) and x becomes the independent variable. In this case, it can be shown that the elasticity of demand is given by E(x)= -g(x)/xg'(x) . Use the given price-demand equation to find the values of x for which demand is elastic and for which demand is inelastic. p=g(x)=9000-0.1x^2
