WebFree Pre-Algebra, Algebra, Trigonometry, Calculus, Geometry, Statistics and Chemistry calculators step-by-step WebFor example, f (x) = (x 2 + x - 2) / (2x 2 - 2x - 3) is a rational function and here, 2x 2 - 2x - 3 ≠ 0. We know that every constant is a polynomial and hence the numerators of a rational function can be constants also. For example, f (x) = 1/ (3x+1) can be a rational function.

WebSolution: Function f: R → R is defined by f (x) = ex. Let x1, x2 ∈ R and f (x1) = f (x2) or ex1 = ex2 or x1 = x2. Therefore, f is one-one. Let f (x) = ex = y. Taking log on both sides, we get x = logy. We know that negative real numbers have no pre-image or the function is not onto and zero is not the image of any real number. WebFinal answer.

(b) Since t2/2 is convex we have t2/2 ≥ x2/2+x(t−x) = xt−x2/2. This is the general inequality g(t) ≥ g(x)+g′(x)(t−x), which holds for any diﬀerentiable convex function, applied to g(t) = t2/2. Another (easier?) way to establish t2/2 ≤ −x2/2+xt is to note that t2/2+x2/2−xt = (1/2)(x−t)2 ≥ 0. Now just move x2/2−xt to the other side. north east smart ports testbed
