6.5 Notes Square Root and Cube Root Functions y x y3 x Domain: Range: Domain: Range: **When making the table, try to use values (inside the radical) that you can take the cube/square root of. It will make simplifying without a calculator easier! You can still use other values, just be prepared to use a calculator! ya xh k y a3 x h k (Recall vertex form!!!) h = horizontal units k = vertical units y x 1 3 vs. y x ** y x 1 3 has a starting point of (-1, 3), whereas y x has a starting point of (0,0). So we can say that the graph of y x becomes y x 1 3 when it is moved 1 unit to the left, and three units down. Example 1: Explain how to obtain the graph of y 3 x 2 1 from the graph of y 3 x . Example 2: Explain how to obtain the graph of y x45 from the graph of y x . Example 3: Graph y 2 x 4 1. State the domain and range. Domain: Range: Example 4: Graph y 23 x 3 1. State the domain and range. Domain: Range: HW: p. 449 # 4, 6, 9, 10, 12, 16, 20, 22, 24
