"The bathtub curve is a particular shape of a failure rate graph. This graph is used in reliability engineering and deterioration modeling. The 'bathtub' refers to the shape of a line that curves up at both ends, similar in shape to a bathtub. The bathrub curve has 3 regions: 1. The first region has a decreasing failure rate due to early failures. " - Reliability curve distribution
