Answer:

Step-by-step explanation:
We are given that 
Initially the difference between the cake's and the cooler's temperature ,a=50 degree Celsius

We have to find the function that gives the temperature difference in degrees Celsius D(t).
We know that 

Substitute the values

Answer:
F(m) = -12
Step-by-step explanation:
Given the function: 
 
 
When m = 4, we substitute the variable 'm' for the number 4: 

F(m) = 256 - 384 + 80 + 40 - 4
F(m) = -12
