If the function y = f(x) is an even function, then which of the following is true? A. f(-x) = -f(x) B. f(-x) = f(x) C. f(-x) = 0 D. f(x) = 0 相关知识点: 试题来源: 解析 B。偶函数的定义是 f(-x) = f(x)。反馈 收藏 ...
解析 f is an odd function, so f(-x)=-f(x). g is an even function, so g(-x)=g(x). Then (f⚬g)(-x)=f(g(-x))=f(g(x))=(f⚬g)(x). So f⚬g is even. Also, (g⚬f)(-x)=g(f(-x))=g(-f(x))=g(f(x))=(g⚬f)(x), so g⚬f is even....

Which of the following is an even function? A. f(x)=xcosx B. f(x)=x2lnx C. f(x)=sinxx3 D. f(x)=x−2 E. f(x)=x2tanxEven FunctionAn even function is a function that is symmetr...
Main Functions in C Programming In C, even if you don’t use user-defined functions or a library, you mustuse the main function, as it is the first function that is executed when the program is run. The main function can call other functions to perform specific tasks. The exit status ...
解析 C Recall that a function is even if it is symmetric with respect to the y-axis and f(-x)=f(x).Graph the functions on your calculator to determine which one has y-axis symmetry. f(x)=-x^2+1 is the correct answer choice.反馈 收藏 ...
Given f is an even function, which of the following must be true? There may be more than one correct answer. Circle all that are correct. ( ) A. ∫ _(-a)^af(x)=0 B. ∫ _(-a)^af(x)=2∫ _0^af(x) C. ∫ _a^af(x)=0 D. ∫ _(-a)^af(x)=∫ _a^(-a)f(x) ...
If a function is invertible the graph of its inverse is the mirror image of the function iny=x.Iff−1(x)is the inverse function of f(x), thenf(f−1(x))=f−1(f(x))=x. Iff(x)=ln[(100+x)ex3(100−x)],then the graph off−1(x)will be symmetrical aboutx+y=1 ...
