part 2 of 3
○ the function is never decreasing.
○ the function is sometimes decreasing.
decreasing interval: ☐
○ the function is always decreasing.
part 3 of 3
○ the function is never constant.
○ the function is sometimes constant.
constant interval: ☐
○ the function is always constant.

Explanation:

To solve this, we need the graph of the function (not provided here). However, for typical function analysis:

Part 2 (Decreasing Interval):

• If the function’s slope is always negative (e.g., \( y = -x \)), choose "The function is always decreasing" and input \( (-\infty, \infty) \).
• If it decreases only on a subset (e.g., \( y = x^2 \) decreases on \( (-\infty, 0) \)), choose "The function is sometimes decreasing" and input the interval.
• If slope is never negative (e.g., \( y = x^2 \) for \( x \geq 0 \)), choose "The function is never decreasing".

Part 3 (Constant Interval):

• If the function’s slope is always 0 (e.g., \( y = 5 \)), choose "The function is always constant" and input \( (-\infty, \infty) \).
• If it is constant only on a subset (e.g., a piecewise function), choose "The function is sometimes constant" and input the interval.
• If slope is never 0 (e.g., \( y = x \)), choose "The function is never constant".

Since the graph is missing, assume a common case (e.g., \( y = -x \) for decreasing, \( y = 5 \) for constant):

Part 2 Answer (Example):

• The function is always decreasing.
• Decreasing interval: \( (-\infty, \infty) \)

Part 3 Answer (Example):

• The function is never constant.

(Note: Replace with actual graph - derived intervals/choices when the graph is provided.)
