9/28/23, 9:50 PM PreCalculus (23-24) Chapter 1 Test 7. Graph the function s(x) = |x + 7|. Then answer the following questions. (a) On what interval, if any, is the function increasing? Decreasing? (b) Is the function odd, even, or neither? (c) Give the function's extrema, if any. (d) How does the graph relate to a graph of one of the twelve basic functions? Graph the function s(x) = |x + 7|. Choose the correct graph below. O A. OB. O C. (a) On what interval, if any, is the function increasing? Decreasing? O A. f is increasing on the interval and decreasing on the interval . (Type your answers in interval notatic O B. f is increasing on the interval . (Type your answer in interval notation.) O C. f is decreasing on the interval . (Type your answer in interval notation.) O D. f is neither increasing nor decreasing. (b) Is the function odd, even, or neither? O A. The function is neither even nor odd. O B. The function is even. O C. The function is odd. (c) Give the function's extrema, if any. The function has a (1) - value of at x =[ (d) How does the graph relate to a graph of one of the twelve basic functions? The graph is the (2) function after a (3) shift (4) unit ( s ) .
