Question

What is dcreasing function ?​

Answer 1

In a function when variable Y is a function of X , then it is said to be decreasing function if the value of Y decreases corresponding to the increase in the value of X.

=> For Example:

Demand function is a decreasing function. The slope of decreasing function is always negative.The graph of decreasing function slopes downward from left to right.

Answer 2

Answer:

The derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′(x)> 0 at each point in an interval I, then the function is said to be increasing on I. f′(x) < 0 at each point in an interval I, then the function is said to be decreasing on I.
