Yesterday at 12 a. m. (midnight) the temperature was 1.5o F . The temperature change in the next 8-hour period of time was - 4⁄5 degree per hour. The temperature change for a 3-hour period after that was 3⁄4 degree per hour. 1. What was the temperature at 11:00 a. m.?
2. What was the change in temperature from midnight to 11 a. m.?

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
