How do you determine the intervals on the function f(x)= x^1/3 (x^2-112) is increasing or decreasing ?
asks to give Use symbolic notation and fractions where needed. Give your answers as intervals in the form (∗,∗.
∗,∗.) Use the symbol ∞
∞ for infinity, ∪
∪ for combining intervals, and an appropriate type of parentheses "(", ")", "[", or "]" depending on whether the interval is open or closed. Enter ∅
∅ if the interval is empty.)
f is increasing when x ?
f is decreasing when x ?
