For each displayed graph, the dependent and independent variables, including the possible situations they represent, are as follows:
Graph a:
Dependent Variable: Height
Independent Variable: Time
Possible Situation: This graph can represent the trajectory of a ball being thrown and then falling back down due to gravity. The peak of the graph represents the highest point reached by the ball.
Key Points/Changes: The ball starts at a certain height, increases to its peak height, and then falls back down.
Graph b:
Dependent Variable: Temperature
Independent Variable: Time
Possible Situation: This could represent daily temperature variations over a while, showing that temperature rises during the day and falls at night.
Key Points/Changes: There are consistent cycles of increase and decrease in temperature.
Graph c:
Dependent Variable: Stock Price
Independent Variable: Time
Possible Situation: This graph can represent the fluctuating prices of a stock over time. It shows two complete cycles of increase and decrease in stock price.
Key Points/Changes: The stock price increases to a peak before falling back down, indicating volatility in the market.
The two main variables, depicting relationships, are the independent variable and the dependent variable.
The independent variable causes a change in the dependent variable.
