A high white blood cell count can indicate that the patient is fighting an infection. A doctor is monitoring the number of white blood cells in one of her patients after receiving antibiotics. The lab returns the following data.
Hour 0 12 24 36
White blood cells (cells mcL⁻¹) 12500 11000 9680 8518.4
Create a general formula to model the patient's white blood cell count at any given time. Use your general formula to calculate the number of white blood cells this patient will have after three days. Round the answer to the nearest whole number and write in cells mcL⁻¹. Discuss the limitation of your general formula.
