Parent Functions and Their Key Features Unit I Assessment Re-take Directions: Read all directions carefully and answer each problem completely. Box, highlight, or circle your answers. True or False: Read each statement. Write T for true, F for false. If the statement is false, replace the key word with a word that will make the statement true. 1. If a function crosses an axis at (0, b) this location is known as a y-intercept of the function. 2. The function f(x) = 4* has a y-intercept of (0, 4). 3. If f (x) = Vx - 5has a reflection about the x-axis, its new function is f (x) = -Vx - 5. 4. If you have a translated function in the form f(x) = (x + h)? - k, the graph is shifted h units left, and k units up. 5. The quadratic function f (x) = x2 + 2 has a range of (co, co). 6. The domain for a function is the set of all possible outputs. Matching: Match the Domain and Range to each function. Some letters may be used more than once and some may not be used at all! A.
