WebThe x values are the domain and, as you say, in the function y = x^2, they can take any real value. However, the values that y can take (the range) is only >=0. (Notwithstanding that the y codomain extents to all real values). 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. how many iits in india https://bobtripathi.com

Web(a) f′′(x) ≤ 0 for x ≥ 0. (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. http://m.1010jiajiao.com/gzsx/shiti_id_0faf76026c6e47b3af59a97aa8142a9c Web设函数f(x)=ax3-3x+1(x∈R),若对于任意x∈[-1，1]，都有f(x)≥0成立，则实数a的值为（ ） ... （2）a<0时，f’(x)=3ax^2-3<0,f(x)是减函数，其最小值为f(1). 若对x∈[-1,1],f(x)≥0恒成立，则需f(1)≥0 即a-3+1≥0 a≥2 又因a<0 所以此时无解. howard carpendale hello again songtext
