Lecture-I 02.05.2025 Graph of Functions: Functions Algebra Polynomial 2 Rational 3. Irrational 4. Piecewise Transcedent 1. Trigonometric 2. Exponential 3. Logarithmic 4 Geometrical curve Polynomials ( f:TR→R ) 1. f(x) = x set of real no. Input: x10-11 | -0.5/2 1000 Output: fix 0-110.5 2 1000 Ex: 2 f(x) = 2 if x = 1000 | f(1000) = 2 1 لا constant Function f(10)=2 f(-1)=21 2 2 x)=22 f(0)=2 ( -4-3-2-1 1 2 3 4 5 + 1000 dom f = R Inbut Range f= {2} out but Range f = { f(x) : xe domainfi {output points} Domain f = { input points}. Ex: f(x) = x f(1)= + = 1, +(2)= = f (3) dehind f(0)=N Now, f(-1) = + = -1 f(-2) = (-2)= Input points are all real no. except zero. Dom f = R\{0} set of real no. minus. singleton zero
