Johan ran some maintenance programs on a server. The graph below models the available RAM on the server from the moment these programs started running until they completed.

**Graph Description**

- The graph is a plot of Available RAM (in Percentage) over time (in Minutes).
- The x-axis represents the time in minutes, ranging from 0 to 9.
- The y-axis represents the Available RAM in percentage, ranging from 0 to 40.
- The graph shows a curve starting from a higher RAM percentage, decreasing to a minimum point, then increasing again.
- The graph illustrates how the available RAM changes during the execution of programs over time.

**Question 4 of 11**

**Identify and interpret the function’s minimum.**

- ○ The function’s minimum is 4.8 at x = 4.4. It implies the server had the least amount of available RAM, 4.8%, 4.4 minutes since the programs started running.
  
- ○ The function’s minimum is 4.4 at x = 5.8. It implies the server had the least amount of available RAM, 5.8%, 4.4 minutes since the programs started running.
  
- ○ The function’s minimum is 4.8 at x = 4.4. It implies the server had the least amount of available RAM, 4.4%, 4.8 minutes since the programs started running.
  
- ○ The function’s minimum is 4.4 at x = 5.8. It implies the server had the least amount of available RAM, 4.4%, 5.8 minutes since the programs started running.

**Firework Trajectory Analysis**

Harry runs a firework business and needs to calculate the height of fireworks in flight. He fires a firework into the air from a hill 100 feet above sea level. The height of the firework's trajectory can be modeled by the polynomial function shown in the graph below.

**Graph Description:**

- The graph represents the height of a firework over time.
- The x-axis displays time in seconds, ranging from 0 to 4.8 seconds.
- The y-axis represents height in feet, with a range from 0 to 160 feet.
- The curve is parabolic, indicating the path of the firework as it ascends and then descends.
- The firework reaches its maximum height at a specific point on the graph.

**Question 10 of 11:**

**Identify and interpret the function’s maximum.**

- ( ) The function’s maximum is 1.7 at x = 147. It implies the firework will reach its maximum height of 147 feet 1.7 seconds after it is fired.
- ( ) The function’s maximum is 1.7 at x = 141. It implies the firework will reach its maximum height of 141 feet 1.7 seconds after it is fired.
- ( ) The function’s maximum is 147 at x = 1.7. It implies the firework will reach its maximum height of 147 feet 1.7 seconds after it is fired.
- ( ) The function’s maximum is 141 at x = 1.7. It implies the firework will reach its maximum height of 141 feet 1.7 seconds after it is fired.
