What is the formula of the graph? Steps for that only please

Use the graph of f to determine each of the following (a) the domain off (b) the range of f (c) the zero (s) of f (d) f(3.5) (e) the intervals on which f is increasing (f) the intervals on which f is decreasing (g) the values for which f(x) lessthanorequalto 0 (h) any relative maxima or minima (i) the value(s) of x for which f(x) = 3 (j) Is f(2) positive or negative? (a) The domain off is (Type your answer in interval notation.) (b) The range of f is (Type your answer in interval notation.) (c) The zero(s) of f are -2 and (d) f(3.5) (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.) (g) Which interval or union of intervals represents the values for which f(x) lessthanorequalto 0? Select the correct choice below and fill in the answer boxes to complete your choice.

Explanation / Answer

a.From the graph we can say that domain=(-infinity,4]

b.And the range is (-infinity,3]

c. Zeroes are x=-2 and x=4

d. f(3.5) =1

d.
