A culture is started with 50,000 bacteria. The table shows the number of bacteria remaining after an antibiotic is added to the culture. The table at the right shows the number of bacteria after the antibiotic is added. time in hours | number of bacteria
o|50000
1|42100
2|35448
3|29847
4|25131
a find an exponential model that is a reasonable fit for the data
how long will it take for the number of bacteria to fall below 5,000
c what is the y intercept of your function what does it mean in the context of the problem
d .what are the values a and b for your function what do these values mean in the context of the problem
e what are the real world domain and range of the function express each using inequalities
graph the function
