1.	Find the domain of the function f(x)= x2 + 3x +5 / x2 - 5x +4{ Example 21 of Ncert Ch 2 } EXPLAIN
Answer» The given function should be true for all values.Splitting the denominator, we get x=1,4.This implies that when we put the values 1 and 4 in the equation of the denominator,the value is zero. A fraction with zero as the denominator cannot be defined. If we will put any other value other than 1 and 4,we get a fraction with non-zero denominator which is defined. So the function is true for all values of x other than 1 and 4.Hence the domain is R-{1,4}. Jdvjk
