Question 1138873: Help with exponential functions homework.
A population of yeast cells can double in 2 h. Assume an initial population of 120 cells.
a) Write an equation that can be used to determine the population of cells at t hours.
b) Use your equation to determine the population after 210 min.
c) What are the domain and range for this situation?

t in hours
p in count of cells

p=120%282%29%5E%28t%2F2%29 p=120*2^(1/2)



Range: 120 and greater
Domain: Real numbers greater than or equal to 0

210 minutes is t=210%2F60=3.5hours.
