Step-by-step explanation
an exponential function is given by:

so
Step 1
Set the equations
a) initial population = 2363
time=0
replace

b) If the number of bacteria doubles every 157 minutes

so, the function is

Step 2
what will the population be 314 minutes from now?
Let
time=x =314
replace

therefore, the answer is
9452
