the graph shows the altitude of a bird over time. select all the intervals on which the graph of the function is not decreasing. altitude time (1) (2) (3) (4) review progress question 13 of
Answer
Explanation:
Step1: Understand non - decreasing
A function is non - decreasing when its graph either goes up or is horizontal.
Step2: Analyze intervals
In interval (1), the graph is going up (altitude increasing with time), so it is non - decreasing. In interval (2), the graph is horizontal (altitude constant with time), so it is non - decreasing. In interval (3), the graph is going down (altitude decreasing with time), so it is not non - decreasing. In interval (4), the graph is horizontal (altitude constant with time), so it is non - decreasing.
Answer:
Intervals (1), (2), (4)
