Algebra 1 Warm Ups 9/25 - 9/28

9/25 Josh hit a ball straight up into the air. The equation below describes the height of the ball (h) in meters, as a function of (t) in seconds. What is the height of the ball after 3 seconds? 2. If and t then what is the value of f(x) + g(x)?

9/26 1. Solve: 2. Use graph paper and staple to your warm up. Graph the line y = -3x + 2. 3. Which graph to the left represents a function?

9/27 1. If then what is f(2)? 2. Use graph paper stapled to your warm-up. Graph the line x + 3y = 9. 3. Let C=16 and D =√2 Which of the following is an irrational number? a. C * C b. D * D c. C + C d. C * D

1. Will E. Coyote is about to roll a boulder off a cliff to hit Road Runner. He is going to roll the boulder from a height of 160 feet. The following graph shows the height of the boulder with respect to time. At what time does the boulder hit the ground? 2. Use the graph paper. Graph the inequality y > 1/3x - 2. In your warm up box, name one point that represents a solution to the above inequality. 3. Convert 25 days to hours.
