Sodium-24 is used in diagnosing circulatory disease. A function for determining the amount of a 100-gram sample that remains after h hours is s ( h ) = 100 ( β 2 ) β 2 h 15 s ( h ) = 100 ( 2 ) β 2 h 15 . The half-life of sodium-24 can be found by rewriting this function to use a base term of 1 2 1 2 . Which function represents the half-life of sodium-24?
