Would you please help me solve these!

both positive. Use the price-demand equation to find the values of p for which demand is elastic and the values for which demand is inelastic. Assume that price and demand are x = f(p) = 1452 - 3p2 The values of p for which demand is elastic are expression.) (Simplify your answer. Type your answer in interval notation.
