Question 1

Determine where the given function is increasing and where it is decreasing. 

y = x3 - 3x2 + 4x - 4
◦ Decreasing on (-∞, -1) and (1, ∞), increasing on (-1, 1)
◦ Increasing on (-∞, ∞)
◦ Increasing on (-∞, -1) and (1, ∞), decreasing on (-1, 1)
◦ Increasing on (-∞, 1), decreasing on (1, ∞)

Question 2

Determine where the given function is increasing and where it is decreasing. 

f(x) = x3 - 12x - 2
◦ Decreasing on (-∞, -2), increasing on (-2, ∞)
◦ Decreasing on (-∞, -2) and (2, ∞), increasing on (-2, 2)
◦ Increasing on (-∞, -4) and (4, ∞), decreasing on (-4, 4)
◦ Increasing on (-∞, -2) and (2, ∞), decreasing on (-2, 2)
