Let T denote the temperature, in degrees, of a cake t minutes after it is placed in the oven. Let
denote the difference, in degrees, between the temperature of the oven and the temperature of the cake. Then D satisfies the equation of change
.
A: What can you conclude about the function ?B: If the temperature of the cake batter is initially 71 degrees, find a formula that gives D in terms of t. Write your answer using the alternative form for an exponential function.C: Find a formula that gives T in terms of t.
