Problem 1 Got It?

  1. Graph the three functions on the same plane at desmos.com.
  2. Zoom and pan your graph to establish an appropriate viewing window. Consider the similarities and differences between the graphs.
  3. Think about the domain, range, intercepts, asymptotes, etc., and how they relate to the equation of each function.
  4. Take a screenshot of your graph and upload or paste it onto the Formative canvas.
y=\frac{6}{x}, y=\frac{8}{x}, y=\frac{12}{x}

Problem 5 Got It? The junior class is renting a laser tag facility with a capacity of 325 people. The cost for the facility is $1200. The party must have 13 adult chaperones.

Respond to each question on the right with the appropriate response from the left.

  • All real numbers
  • Whole numbers from 1 to 312
  • Integers from -13 to 325
  • 173 students
  • 162 students
  • 160 students
  • If every student who attends shares the facility cost equally, what function models the cost per student C with respect to the number of students n who attend?
  • What is the domain of the function? Consider only the domain values that make sense in the context of the problem.
  • How many students must attend to make the cost per student no more than $7.50 per student?
