The temperature of an object in a experiment is T(t) = 60(1/3)^t + 10, where T is the temperature in degrees C and t is time in seconds.
What is the domain and range of this situation?

  1. The important term to consider is
    60(1/3)^t, which has a domain of R (all real) and a range of (0,+∞).
    Therefore
    dom T(t) = R
    ran T(t) = (10,∞)
