2. Let f be the function given by f(x) = 300x-x3. On which of the following intervals is the function f increasing? (A) (-∞, -10] and [10, ∞) (B) [-10, 10] (C) [0, 10] only (D) [0, 10√3] only (E) [0,00)

(b) What are the domain and range of the function y = f(x + 2)? (Use symbolic notation and fractions where needed. Give your answers as intervals in the form (*, *). Use the symbol ∞ for infinity and the appropriate type of parenthesis "(", ")", "[", or "]" depending on whether the interval is open or closed.) D = R =

Find the interval on which F is DECREASING
