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.

A function is surjective or onto if each element of the codomain is mapped to by at least one element of the domain. In other words, each element of the codomain has non-empty preimage. Equivalently, a function is surjective if its image is equal to its codomain. A surjective function is a surjection. & Let f : A ----> B be a function. There exists even a single element in B having no pre-image in A, then f is said to be an into function. ....
