Topics Covered in Exercise 6.2 Class 12 Mathematics Questions
Ex 6.2 class 12 maths ch 6 covers the concept of increasing and decreasing functions. You can check a detailed explanation of this topic provided below.
1. 
Increasing and Decreasing Functions 

Increasing and Decreasing Functions  If the first derivative in a range is positive, the function is increasing in that range; conversely, if the derivative is negative, the function is decreasing in that range. For example, When a given function, y = F(x), has a value that increases as x increases, it is said to be an increasing function; conversely, if y's value decreases as x increases, it is said to be a declining function.
Let I be an interval contained in the domain of a real valued function f. Then f is said to be
(i) increasing on I if x_{1} < x_{2} in I ⇒ f(x_{1} ) < f(x_{2} ) for all x_{1} , x_{2} ∈ I.
(ii) decreasing on I, if x_{1} , x_{2} in I ⇒ f(x_{1} ) < f(x_{2} ) for all x_{1} , x_{2} ∈ I.
(iii) constant on I, if f(x) = c for all x ∈ I, where c is a constant.
(iv) decreasing on I if x_{1} < x_{2 }in I ⇒ f (x_{1} ) ≥ f(x_{2} ) for all x_{1} , x_{2} ∈ I
(v) strictly decreasing on I if x_{1} < x_{2} in I ⇒ f(x_{1} ) > f(x_{2} ) for all x_{1} , _{2} ∈ I
Let x_{0} be a point in the domain of definition of a real valued function f. Then f is said to be increasing, decreasing at x_{0} if there exists an open interval I containing x_{0} such that f is increasing, decreasing, respectively, in I.
Theorem 1: Let f be continuous on [a, b] and differentiable on the open interval (a,b). Then
(a) f is increasing in [a,b] if f ′(x) > 0 for each x ∈ (a, b)
(b) f is decreasing in [a,b] if f ′(x) < 0 for each x ∈ (a, b)
(c) f is a constant function in [a,b] if f ′(x) = 0 for each x ∈ (a, b)

Frequently Asked Questions
If the value of y increases as the value of x increases for a function y = f(x), then the function is called an increasing function.
If the value of y decreases on increasing the value of x for a function y = f(x), the function is said to be decreasing.
