Unit One Test Review Functions and Absolute Value
For the test, I need to know how to… • Find the domain and range of a function given its graph • Perform operations on functions (add, subtract, multiply, divide) • Compose two functions • Find and verify inverses • Graph absolute value functions • Solve absolute value equations and inequalities
f(x) = 3x – 5 g(x) = -2x + 1 • Find f(x) – g(x)
f(x) =x²+ 1 g(x) = x – 5 • Find f(g(x))
f(x) = 3x – 5 g(x) = -2x + 1 • Find g(f(-3))
f(x) = 3x – 5 g(x) = -2x + 1 • Find f(x) g(x)
f(x) =x²+ 1 g(x) = x – 5 • Find g(f(x))
Verify that the two functions are inverses F(x) = 0.5x + 4 F -1(x) = 2x – 8

Find the inverse Function y = 3x +7
Find the inverse Function y = -2x + 6
Find the Vertex Point y = -2|x – 4| + 5
Find the Vertex Point y = 3|2x + 6| - 1
Describe the Transformations y = -|x + 3| - 8
