If f(x) is an invertible function and g(x)=2f(x)+5, then the value of g−1(x)is (a)2f−1(x)−5 (b) 12f−1(x)+5 12f−1(x)+5 (d) f−1(x−52) View Solution If f(x) is an invertible function and g(x)=2f(x)+5, then the value of g−1(x)is (...
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 ...
1.If a function has an inverse function,then the inverse function is one-to-one.2.If a function is diffrentiable,the f'(x) is one-to-one.需要理由和举例. 答案 第一个是对的!存在反函数的条件是原函数必须是一一对应的,也就是说原函数有反函数,则反函数一定是一一对应的!第二个是错的!可微...
If the function f(x) = x³ has an inverse function g(x), then g(8)=? A. 2 B. 3 C. 4 D. 5 相关知识点: 试题来源: 解析 A。因为 f(x) = x³,其反函数 g(x) = ∛x。当 f(x)=8 时,x = 2,所以 g(8)=2。反馈 收藏 ...
Inverse Function:In mathematics, the inverse is the opposite of that function. It is also used to find the values of the trigonometric functions. If we have given a function of y in terms of x, then we can write it in terms of y. A function that...
