The amount of yeast, g grams, in a sugar solution can be modelled by the function,
g(t) = 10 − k(c−t) for t ≥ 0
where t is the time in minutes.
The graph of g(t) is shown.
The initial amount of yeast in this solution is 2 grams.
The amount of yeast in this solution after 3 minutes is 9 grams.
Write down the maximum amount of yeast in this solution.
