Question

I need help with questions 1-5 please. I am having a hard time understanding what is being asked.

For t > 0, let H (t) = 68 +93(0.91) represent the temperature of a cup of coffee in
degrees Fahrenheit t minutes after it is brought to class.
1. Find formulas for H (t+15) and H (t) + 15.
2. Graph H (t), H (t + 15), H (t) + 15.
3. Describe the transformations of the graph of H (t) that will result in the graphs of
H (t+15) and H (t) + 15.
4. Find lim+→∞ H(t) and describe the practical significance of the horizontal
asymptote.
5. Describe in practical terms a situation modeled by the function H (t + 15). Do the
same for H (t) + 15. [Hint: Think about your work from the previous part.]
