The refrigerator doesn't work.

skullpatrol · Answer

$$\Huge y=e^{x}$$

anonymous · Answer

It is a word problem for an exponential function for melting

anonymous · Answer

@skullpatrol what would the x be

skullpatrol · Answer

The variable looks like time.

anonymous · Answer

I think SP's first answer works well, after all it doesn't ask for an exponential function that describes the situation.

anonymous · Answer

yes it does ask to use the facts to write an exponential function

anonymous · Answer

OK... 20-e^(-kx) = y  (x in minutes, y in degrees)
then find k using 6,8

anonymous · Answer

20-e^(-kx) = y  
20-e^(-k*6) = 8
...
You got it yet?

anonymous · Answer

I do not know how to solve for that
