  1. Warm up • Find f(6). • Find g(-1). • Given r(x) = 2x – 1, evaluate the domain {0, 1, 2, 3}. What is the range of r(x)? 4 3 Range: {-1, 1, 3, 5}

  2. Linear, Exponential, or Neither

  3. For each representation of a function, decide if the function is linear, exponential, or neither. Give reasons for your answer.1. Linear

  4. For each representation of a function, decide if the function is linear, exponential, or neither. Give reasons for your answer.2. Exponential

  5. For each representation of a function, decide if the function is linear, exponential, or neither. Give reasons for your answer.3. This function is decreasing at a constant rate. Linear

  6. For each representation of a function, decide if the function is linear, exponential, or neither. Give reasons for your answer.4. A person’s height as a function of a person’s age (from age 0 to100). Neither

  7. For each representation of a function, decide if the function is linear, exponential, or neither. Give reasons for your answer.5. Linear

  8. For each representation of a function, decide if the function is linear, exponential, or neither. Give reasons for your answer.6. Each term in a sequence is exactly 1/3 of the previous term. Exponential

  11. Linear vs. Exponential Functions Task Classwork

  12. Option 1: You can have $1000 a year for twenty years.Option 2: You can get $1 the first year, $2 the second year, $4 the 3rd, doubling the amount each year for twenty years. Which option gives you more money?

  13. Raking leaves Task Classwork

  14. 1. Two dollars for each bag of leaves.2. Or two cents for one bag, four cents for two bags, eight cents for three bags, and so on with the amount doubling for each additional bag. If Celia rakes five bags of leaves, should she opt for payment method 1 or 2? What if she rakes ten bags of leaves?

  15. 1. Two dollars for each bag of leaves.2. Or two cents for one bag, four cents for two bags, eight cents for three bags, and so on with the amount doubling for each additional bag. 2. How many bags of leaves does Celia have to rake before method 2 pays more than method 1?

  16. 1. Two dollars for each bag of leaves.2. Or two cents for one bag, four cents for two bags, eight cents for three bags, and so on with the amount doubling for each additional bag. 3. Describe the differences in payment plans.

  17. 1. Two dollars for each bag of leaves.2. Or two cents for one bag, four cents for two bags, eight cents for three bags, and so on with the amount doubling for each additional bag. 4. Describe the difference in the way the payment grows in the table and on the graph.

  18. 1. Two dollars for each bag of leaves.2. Or two cents for one bag, four cents for two bags, eight cents for three bags, and so on with the amount doubling for each additional bag. 5. Is this growth situation continuous or discrete? How do you know?
