Area bounded between curves help?

Question

f(x) = e^x g(x) = e^-2x 

and the line y = 6 
---------------------------------------------------------- 
Answer choices 
1. Area = 3/4 (6 ln(6) - 5) sq. units 
2. Area = 3/4 (6 ln(6) + 5) sq. units 
3. Area = 9 (ln(6) - 1) sq. units 
4. Area = 9 (ln(6) + 1) sq. units 
5. Area = 9/2 (ln(6) - 1) sq. units 
6. Area = 3/2 (6 ln(6) - 5) sq. units
