1 answer:
Answer(a):
Exponential growth formula is given by

Where preset population = P= 775
Rate of increase = r = 51% = 0.51
t= number of years
A= Future value.
Plug these values into above formula:


Hence required exponential function is 
Answer(b):
plug t=10 years

which is approx 47761.
Answer(c):
Plug A=1150




0.957643654334=t
Which is approx 1 year.
