Increasing Decreasing Functions

Identify where the function is decreasing.

• x < 0

• x > 0

• x < -3 , x > 3

• -3 < x < 3

What do we know about the slope for increasing functions?

• The slope is positive

• The slope is negative

• There is zero slope

What is the decreasing interval(s) on the function shown?

The intervals in which the function f given by f (x) = x² – 4x + 6 is increasing is

• none of these

• none of these

The interval on which the function f (x) = 2x³ + 9x² + 12x – 1 is decreasing is:

y = x (x – 3)² decreases for the values of x given by :
