Domain, Range, Increasing and Decreasing Parabolas

Where is the function decreasing?

• (-∞, -1)

• (-1, ∞)

• (-∞, 3)

• (-∞, ∞)

Identify where the function is increasing and where it is decreasing.

• increasing x > -1 and decreasing x<-1

• increasing x < -1 and decreasing x > -1

• increasing ꓣ and decreasing nowhere
