Increasing and Decreasing Functions

It’s 8 AM and you’re feeling terrible. Your temperature is 101°. The only prescription is constructing a graph showing your body temperature as a function of the time of day. You decide to let represent the number of hours after 8 AM and your temperature at time .

Don’t Get Sick

YES! Your temperature starts to decrease. It reaches normal (98.6° F) by 11 AM. Feeling energized, you construct the graph below.

From what values does the temperature decrease?

After creating the first graph drains you of energy, your temperature starts to rise, until it reaches 100°.

From what values does your temperature increase?

By 3 PM, your temperature is still at 100°.

From what values does your temperature stay constant?

State the intervals on which each function is increasing, decreasing, or constant.

P. 223 #1-12 Use the graph to determine

◦ Intervals on which the function is increasing, if any.

◦ Intervals on which the function is decreasing, if any.

◦ Intervals on which the function is constant, if any.
