a. (-∞, ∞)
b. (-∞, 0.5) and (2.5, ∞)
c. (0.5, 2.5)
d. ∞
e. -∞
f. Minimum
g. Maximum
h. (1.5, ∞)
i. (-∞, 1.5)
j. x = 1.5
k. y = 4

Answer 1

1. Increasing: (0, -5) to (0.5, 0) and (2.5, 0) to (1.5, 4)
2. Decreasing: (1.5, 4) to (2.5, 0)
3. Positive: None
4. Negative: (0, -5) to (0.5, 0) and (2.5, 0) to (1.5, 4)
5. Axis of Symmetry: x = 1.5
6. Does this function have a minimum or maximum? Minimum at (1.5, 4)
