Question - 1: - Find the exponential function f(x)=c . 2^{b x} whose graph is (0,2) & (1,3). Find the value of a & b
I have find a & the ans is 2 but I am not getting the right answer of b so please tell me the answer of b
Question - 2: - A bacteria culture initially contains 2500 bacteria and doubles every half hour. The formula for the population is p(t)=2500 e^{kt} for some constant k. (You will need to find k to answer the following.)
Find the size of the baterial population after 80 minutes. ______________
Find the size of the baterial population after 4 hours. ______________
after solving these I have got 11088 for the first one & 639246.8 for the second one but these are not the right answer. Please help me to find the right answers of these questions.
