What's on the worksheet

  1. Use the graphs of two functions to solve equations and inequalities.
  2. Use the left side minus the right side to show a solution lies between two integers.
    x^2 = 7, between 2 and 3x^2 + x = 10, between 2 and 32^x = 3x, between 3 and 43^x = 5 - x, between 1 and 2
  3. Find a linear function whose graph meets a parabola at two given x-values.
  4. Make a table of two functions, find every solution and explain why there are no others.
  5. Solve equations from two graphs that meet at two points, or say why the information is not enough.
  6. Medicine dose problem: model the amount in the blood and compare it with a limit.
