Unit 2 : CALCULAS 1

Function

Q1. Define function.

Ans: A function is a process or a relation that associates each element x of a set X the domain of the function, to a single element y of another set Y (possibly the same set) the codomain of the function. It is generally denoted by letters as f, g, h. I if y is a function of x then y is denoted by the symbol f(x) i.e. y = f(x). Here x is called the independent variable and y is called the dependent variable.

 Ex: y = 2x + 1

Q2. If f(x)=x²-3x+2 find f(3) and (0)

Ans: Here f(x)=x² − 3x+2

. ' . ƒ(1) = 1² −3.1+2

              = 1-3+2 = 0

 . ' .  f(3) =3² -3.3+2

               =9-9+2

               = 2

f(0) = 0² -3.0+2 = 2
