The amount of carbon-14 present in a paint after t years is given by y equals y Subscript o Baseline e Superscript negative 0.00012 t Baseline . The paint contains 27% of its carbon-14. How old are the paintings?

The painting is

Step-by-step explanation:

From the question we are told that

    The amount of carbon present after t year is

               {Note ; This is the function }

Here   is the amount of carbon-14 after time t

        the original amount of carbon-14

Now given that the paint as at now contain 27% of the original carbon-14

  Then it mean that

So the equation is represented as

=>    

=>    

=>  

=>  

=>  

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.
