The graph below shows how the number of grey squirrels living in a forest changes over time. The equation for this graph is S = alt where S is the number
of grey squirrels, t is the time in years and a and b are positive constants.
a) Using the graph, find the constants a and b, a=v2 6:3
b) 1 = 0 on 1" January 2012. Assuming the

population of grey squirrels continues to
grow in the same way, how many squirrels
will there be on 1" January 2017?
