1. can't be determined cause no info given on the rate of which the population is growing.
2. can't be determined/not true because the initial population of a could be less than b.
3. can't be determined/not true because we don't have enough info to tell how fast they grow and decline.
        
                    
             
        
        
        
Answer:
1. g(3) = 1
2. (f + g)(2) = f(2) + g(2) = 2 + 3 = 5
3. f(g(4)) = 2
4. g(f(4)) = 1
5. f(f(4)) = 2
6. g(g(2)) = 1
7. base on the chart, the value 3 of g(x) can be gain only for x = 0

Answer:
Therefore, Steve will paint house for 20.6 days.
Step-by-step explanation:
We know that Steve determines that it would take them 9 days to paint the house together (if they were both healthy) and that it would take Janet (when healthy) 16 days to paint the house alone.
We conclude that in 1 day Janet painted 1/16 of the house. In nine days, Janet painted 9/16 of house.
So, 7/16 of house paint Steve in nine days.
We have the following proportion:

Therefore, Steve will paint house for 20.6 days.
