During motion, we know distance never decreases(ie. It is a monotonically increasing function of time), this implies
speed never decreases(It is also a monotonically increasing function)
speed is always positive
speed is never negative
speed can take any value
Which of the following function is a monotonically increasing function?
Constant functions are Monotonically increasing as well as monotonically decreasing functions
All the monotonically increasing functions are strictly increasing functions.
All the strictly increasing function are monotonically increasing functions.
