Study Notes

Average Rate of Change (AROC)

  • AROC measures the change in a function's value over a specific interval in relation to the change in the input values.
  • Calculated by the formula: AROC = (f(b) - f(a)) / (b - a), where a and b are the interval bounds.

Specific Average Rates of Change Examples

  • For X = -5 to X = 3: AROC is -3/8.
  • For X = -4 to X = 3: AROC is 1/7.
  • For X = -1 to X = 5: AROC is -18.
  • For X = -3 to X = 1: AROC is 5/4.
  • For X = 0 to X = 3: AROC is 2/3.
  • For X = -6 to X = 4: AROC is -1/2.
  • For X = 0 to X = 10: AROC is 3/10.

Key Takeaways

  • AROC values can be positive or negative, indicating intervals of increase or decrease in the function.
  • Understanding AROC is essential for analyzing linear and nonlinear functions in Algebra 2.
