Mahi Kumari 4 years ago

Yaa, you have to solve question by doing imagination that where the functions is increasing and decreasing during solving questions. Like :- (x-3)(x-4)=0 Intially equate orders with zero, we get:- x=3,x=4. (The two critical points). Now the order of (x-3)^1 is 1, which is odd. Then in number line when we move to another point, it remains same degree. Similary for other order.
