Maria created a graph of B(t), the temperature over time. For the interval between t = 3 and t = 7, the average rate of change i
n her graph of B(t) is 8. Which statement must be true? The temperature was 8 degrees higher when t = 7 than when t = 3. The temperature was 8 times higher when t = 7 than when t = 3. The temperature was 32 degrees higher when t = 7 than when t = 3. The temperature was 2 degrees higher when t = 7 than when t = 3.
