What's on the worksheet

  1. Find the missing outputs in each exponential table, then write its rule.
    x: 0, 1, 2, 3 \quad y: 6, ?, 54, ?x: 0, 1, 2, 3 \quad y: ?, 40, 10, ?x: 1, 2, 3, 4 \quad y: ?, 9, ?, 81x: −1, 0, 1, 2 \quad y: 2, ?, 12.5, ?
  2. Maya's ball bounces: write a rule for the bounce height.
  3. Hannah's yeast: use the hourly factor to write and use a rule.
  4. Write the rule of an exponential curve through two labeled points.
  5. Decide whether each table can come from an exponential rule and write it if it can.
  6. Explain why no exponential rule fits three given points, and change one value so it does.
