Question

Determine all intervals on which the graph of f is decreasing. Y y Graph of A 6 4 2 1 -9 -8/-7 -6 -5 -4 -3 -2 1 2 3 8 9 -3 -4 -6 -8

Answer 1

A function is decreasing when the values of the function decreases while the values of x increases.

Based on the previous statement, you can conlude that in the following interval the function is decreasing:

For x/x ∈ (0,3)

You can notice that in the previous interval the function decreases while X increases.
