How Does Adding Liquidity to a Pool Affect Its Resistance to Price Manipulation?

Adding liquidity increases the total value of k in the x · y = k formula, making the price curve flatter. A flatter curve means that a larger trade (more capital injection) is required to cause the same magnitude of price change.
