Una sirena suena cada 10 segundos, otra cada 12 segundos y una tercera, cada 15 segundos. Si a las 6:00 a. M., coincidieron las tres, ¿a qué hora volverán a sonar nuevamente al mismo tiempo?

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
