Question
Classify the critical points as relative maxima, relative minima, or horizontal points of inflection. In each case, check your conclusions with a graphing utility. (If an answer does not exist, enter DNE.)

- **Relative maxima**  
  \((x, y) = \left(1, \frac{29}{6}\right)\)  
  Incorrect (✗)

- **Relative minima**  
  \((x, y) = \left(-2, \frac{28}{3}\right)\)  
  Incorrect (✗)

- **Horizontal points of inflection**  
  \((x, y) = (DNE)\)  
  Correct (✓)

### Consider the following function:
\[ y = \frac{x^3}{3} + \frac{x^2}{2} - 2x + 6 \]

#### (a) Find \( y' = f'(x) \).
\[ f'(x) = x^2 - 1 \]

*Incorrectly computed.*

#### (b) Find the critical values.
(Enter your answers as a comma-separated list.)
\[ x = 1, -1 \]

*Incorrectly computed.*

#### (c) Find the critical points.
\[ (x, y) = \left(1, \frac{16}{3}\right) \]
(Smaller \( x \)-value)

\[ (x, y) = \left(-1, \frac{20}{3}\right) \]
(Larger \( x \)-value)

*Incorrectly computed.*

#### (d) Find intervals of \( x \)-values where the function is increasing.
(Enter your answer using interval notation.)
\[ (-\infty, -1), (1, \infty) \]

*Incorrectly computed.*

#### Find intervals of \( x \)-values where the function is decreasing.
(Enter your answer using interval notation.)
\[ (-1, 1) \]

*Incorrectly computed.*
