To determine which of the situations could describe a specific type of graph, let's summarize the potential growth patterns of each option:
-
Sienna buys a vintage record for $20. Its value appreciates by 20 percent each year.
- This describes exponential growth. The value increases by a constant percentage each year, resulting in a curve that rises gradually. This is often modeled by the equation \(V(t) = 20(1.2)^t\), where \(V(t)\) is the value at time \(t\).
-
Juveldy puts $20 in a high-yield savings account. His investment triples every year.
- This also describes exponential growth but at a faster rate than Sienna's record. The investment triples, which can be represented by the equation \(I(t) = 20(3)^t\). This results in a steeply rising curve.
-
Niall rents a bike for $20 per hour.
- This is a linear situation, where the cost (or value) increases linearly based on time but does not exhibit exponential growth. Therefore, this would produce a straight line, rather than a curve.
-
There are 200 cockroaches in a building, and the population triples every day.
- Similar to Juveldy's case, this is also an example of exponential growth, where the population triples each day, represented by the equation \(P(t) = 200(3)^t\). This would lead to a very steep growth graph.
Given these descriptions, options 1, 2, and 4 exhibit exponential growth, while option 3 exhibits linear growth. The situations that "could describe the graph" of exponential growth are:
- Sienna's vintage record (option 1)
- Juveldy's savings account (option 2)
- The cockroach population (option 4)
If you're looking for exponential growth specifically, options 1, 2, and 4 fit that criteria.
