Part 1: Intervals
Find the open interval(s) on which $f(x)$ is increasing / decreasing / concave up / concave down. Type your answers using interval notation.
1. Increasing: (round your endpoints to the nearest half unit)
2. Decreasing: (round your endpoints to the nearest half unit)
3. Concave Up:
4. Concave Down:
Answer Formats
If necessary, use -INF and INF to denote $-\infty$ and $\infty$.
If the function does not have any, enter NONE.
If the function has more than one, type your answer as a comma separated list. For example: $(a_1, b_1), (a_2, b_2)$.
Part 2: Points
Find the $x$-values(s) where $f$ has a relative maximum / relative minimum / inflection point.
1. Relative Maximum:
2. Relative Minimum:
3. Inflection Point:
