Determine the interval over which function f is continuous. f(x) = :7 (x3 5) Use the union symbol, U, to combine separate intervals and use 95 to indicate an empty set. interval: Verify that the function f (x) = x3 x + 7 has a zero in the interval [3, 0]v Graph the function f using the graphing utilityv 10 Evaluate the function values at the endpoints of the interval [3, 0]. (Use decimal notation. Give your answer to three decimal places if necessary.) r= I: r= Identify why f has a zero on the interval [3, 0]? O f has a zero on [3, 0] because f(3) > 0 and f(0) 0. O f has a zero on [3, 0] because f(3) > 0 and f(0) > 0. O f has a zero on [3, 0] because f(3)
