Doctors treated a patient at an emergency room from 2:00 P. M. to 7:00 P. M. The patient's blood oxygen level L (in percent) during this time period can be modeled by L = −0.270t² + 3.57t + 80.6 2 ≤ t ≤ 7
where t represents the time of day, with t = 2 corresponding to 2:00 P. M.
Use the model to estimate the time (rounded to the nearest hour) when the patient's blood oxygen level was 92%.
