Need help with this question in my homework, an explanation please so I can get it, it's being giving me headache

3. Use the graph of f to determine each of the following (a) the domain of f (b) the range of f (c) the zero(s) off 16 ,- 69 = $ (d) f(5.5) 2 7 (e) the intervals on which f is increasing (f) the intervals on which f is decreasing 8 6 4 2 2 4 6 8 10' (9) the values for which f(x ) 5 0 (h) any relative maxima or minima (1) the value(s) of x for which f(x) = 3 () Is f(4) positive or negative? (a) The domain of fis (Type your answer in interval notation.) ( b ) The range of fis (Type your answer in interval notation.) (c ) The zero (s) of f are 0 and ( d ) f ( 5.5 ) = (e ) The interval on which f is increasing is (Type your answer in interval notation.) (f) The interval on which f is decreasing is (Type your answer in interval notation.) (9) Which interval or union of intervals represents the values for which f(x) S 0? Select the correct choice below and fill in the answer boxes to complete your choice. OA . ( O B. O C. OD. OE. OF . (h) The function has no smallest value over any open interval so there is no relative minimum. The relative maximum of the graph is where f(x) = (1) f(x) = 3 where x = (Use a comma to separate answers as needed.) () Is f(4) positive or negative? O Negative Positive
