Determine the intervals on which the graph of ?=?(?) is concave up or concave down, and find the points of inflection. ?(?) = (?^(2) − 17) ?^? Provide intervals in the form (∗,∗). Use the symbol ∞ for infinity, ∪ for combining intervals, and an appropriate type of parenthesis "(", ")", "[", or "]", depending on whether the interval is open or closed. Enter ∅ if the interval is empty. Provide points of inflection as a comma‑separated list of (?,?)...
