Let the function f be defined by f(z) = . Indicate whether the following statements are 1. True (1) or False (F). You must get all answers correct in order to receive credit. 1. 0 is in the domain of f 2. All positive real numbers are in the domain of f 3. f(z) is never positive. 4. f(z) is never zero. 5. f(z) is never negative. 6. 1 is in the domain of f 7. All negative real numbers are in the domain of f Hint: Draw the graph of f. 2. Find the domain of the function f(z) = V3+ 2x 12 - 81 and write your answer in interval notation. Domain: K Given the graph of / (2) above, find the following and write al Domain of f (=) ( Range ad / (=): The graph of a piecewise function. f(z), is depicted above.
