For x 1, x 2 ∈ R, consider We note that there are point, x1 and x 2 with x 1 ≠ x 2 and f (x 1) = f (x 2), for instance, if we take x 1 = 2 and x 2 = 1/2, then we have f (x 1) =2/5 and f(x 2) =2/5 but 2 ≠ 1/2 Hence f is not oneone Also, f is not onto for if so then for 1∈R ∃ x ∈ R such that f (x) = 1 which gives x/(x 2 1) =1 But there is no such x in the domain R, since theIt follows that f x (t) = e tx for every t in R Lie algebrasThe function fR>Rf (x)= (x1) (x2) (x3) check if it is one one ,onto or bijection The function fR>R f (x)= (x1) (x2) (x3) check if it is one one ,onto or bijection ujjeshaa, 5

F(x)=x/1+x^2 find domain and range
F(x)=x/1+x^2 find domain and range-Suppose you are given the two functions f (x) = 2x 3 and g(x) = –x 2 5Composition means that you can plug g(x) into f (x)This is written as "(f o g)(x)", which is pronounced as "fcomposeg of x"And "( f o g)(x)" means "f (g(x))"That is, you plug something in for x, then you plug that value into g, simplify, and then plug the result into f(x 1)(x 2) (x 2)2 After cancellation, we get lim x!2 (x 1)(x 2) (x 2)2 = lim x!2 (x 1) (x 2) Now this is a rational function where the numerator approaches 1 as x!2 and the denominator approaches 0 as x!2 Therefore lim x!2 (x 1) (x 2) does not exist We can analyze this limit a little further, by checking out the left and right hand limits at
