How can a product have both elastic and inelastic demand?

A product can exhibit both elastic and inelastic demand depending on various factors such as price range, consumer preferences, and availability of substitutes. For instance, a product may have inelastic demand at lower price levels, as consumers consider it a necessity, but become elastic at higher prices when alternatives become more attractive or budgets are strained. Additionally, the time frame can influence demand elasticity; short-term demand may be inelastic, while long-term demand can become more elastic as consumers adjust their behavior.
