Warm Ups 3/2/15 1.Solve the equation: 4 < 4 x Solve √(3x + 13) + 3 = 2x

Warm Ups 3/3/15 3.Solve the equation: x + 4 = x x x + 42 x 2 + 8x Using the function f(x) = √(x – 8) as a guide, write the square root function g(x): The function f(x) is reflected over the x-axis, shrunk by a factor of 1/3, translated left 2 units and translated down 5 units.

Warm Ups 3/4/15 5.Simplify the complex fraction: 6 x x Using the function f(x) = √(x + 1) as a guide, write the square root function g(x), graph it, list three points on the graph, and find the domain and range: The function f(x) is reflected over the x-axis, translated right 6 units and translated up 1 units.

Warm Up 3/5/15 7. Last semester five of Mr. Dewayne’s students built a sailboat in 195 working hours. The time, t, that it takes for a group of students to build a sailboat varies inversely as the number of students, n. Mr. Dewayne uses this data to plan activities for next semester. How many students must Mr. Dewayne get to participate in order to build a sailboat in 70 hours? 8. Graph f(x) > 3 √(-(x + 2))
