Q.1: (Q.1 IN FIRST IMAGE!!)
The population of a specific species of nocturnal mammal is decreasing at a rate of 3.5%/year. The graph models the number of mammals x years after they were originally counted.
Identify and interpret the key features of the exponential function modeled in terms of this situation.
Select EACH correct answer.
Question 1 options:
The y-intercept represents the number of mammals when they were originally counted.
The line y = 0 is an asymptote of the graph.
The y-intercept.is 75.
The y-intercept is 120.
The asymptote indicates that the number of mammals counted when the study began was 120.
The asymptote indicates that as years pass, the number of mammals will approach 0.
The line x = 0 is an asymptote of the graph.
Q.2 ( IMAGE IN SECOND )Once an antibiotic is given, number of bacteria decreases at a rate of 15%/day. There were about 15,000 bacteria prior to the treatment. The graph models the number of bacteria after x days of treatment.
What are the key features of the exponential function modeled in terms of this situation and how can they be interpreted?
Select each correct answer.
Question 2 options:
The line y = 0 is an asymptote of the graph.
The x-intercept is 30.
The line x = 0 is an asymptote of the graph.
The asymptote indicates that there will never be more than 15,000 bacteria.
The y-intercept is 15,000.
The y-intercept represents the number of bacteria when treatment began.
The asymptote indicates that as time increases, the number of bacteria approaches 0.
Q.3 ( Q.3 IN THIRD IMAGE) A local farmer had a mouse problem in his barn. He estimated there were about 800 mice to start with. He adopted some cats and noticed that the number of mice was decreasing by 8%/wk. The graph models the number of mice x weeks after the farmer adopted the cats.
Identify and interpret the key features of the exponential function modeled in terms of this situation.
