![**Determine the intervals on which the given function is concave up or concave down and find the points of inflection.**
The function is given by:
\[ f(x) = (x - 4)(1 - x^3) \]
- **Instructions:** Use symbolic notation and fractions where needed. Give your answer as a comma-separated list of points in the form \((*,*)\). Enter DNE if there are no points of inflection.
**Points of Inflection:** \((x, y) = \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ \)
- **Instructions:** Use symbolic notation and fractions where needed. Give your answers as intervals in the form \((*,*)\). Use the symbol \(\infty\) for infinity, \(\cup\) for combining intervals, and an appropriate type of parenthesis “(“, “)”, “[", or “]” depending on whether the interval is open or closed. Enter \(\emptyset\) if the interval is empty.
