In a typical diabetic the level of insulin might be given by

In a typical diabetic, the level of insulin might be given by the following function: f(t) = {65t + 110 if 0 lessthanorequalto t lessthanorequalto 4 370 if 4

Solution

1) at 10AM that is 5 hours after insulin

so we will be using second function

hence, blood sugar at 10AM is 370

option A

2) at 6PM that is 13 hours after insulin

we will be using 3rd function

f(t) = -80t +1250

= -80(13) + 1250

= 210

option c is correct
