1. Warm Ups Term 4 Week 3

2. Warm Up 4/4/16 1.Graph f(x) = 3 x + 4. State the domain and range. Graph the inverse and state its domain and range. 2.Factor each: a. x 2 – x – 6 b. 4x 2 – 81 c. 3x 2 + 24x + 48

3. Warm Up 4/5/16 3. Find the inverse of f(x) = - 5x + 90 4. Factor to simplify: x 2 – 25 ÷ x 2 – 3x – 10 2x 2 + 5x - 12 x 2 + 9x + 20

4. Warm Up 4/6/16 5. A tank of water holds 220,000 gallons of water. It is leaking at a rate of 4% per month. Write an equation and use it to find how many months it will take for the tank to drop below 100,000 gallons. 6. Solve. Check your solution.

5. Warm Up 4/6/16 5. A tank of water holds 220,000 gallons of water. It is leaking at a rate of 4% per month. Write an equation and use it to find how many months it will take for the tank to drop below 100,000 gallons. What is the rate of change from 14 months to 17 months? 6. Solve. Check your solution.

6. Warm Up 4/7/16 7. Rewrite the logs and evaluate: a. log 2 45 3 b. log 6 32 – log 6 4 + log 6 2 c. log 8 7 + log 8 22 8. x x + 4 – x + 36 x 2 – 16 Add or subtract. Identify any x-values for which the expression is undefined.

7. Warm Up 4/8/16 9. Find the inverse of g(x) = 16 - 2x 3 10. Identify the asymptotes of the function, graph it, and describe how it transformed: f(x) = 1 + 7 x - 4
