一道大学英文数学题 find a formula for the inverse of f.f(x)=5 4x+7 f-1(x)=? 答案 inverse of 就是f(x)的反函数 Let y=f(x)=54x+7, ==> x=(y-7)/54 Hence,f-1(x)=(x-7)/54 . 相关推荐 1 一道大学英文数学题 find a formula for the inverse of f.f(x)=5 4x+7...
一道大学英文数学题 find a formula for the inverse of f.f(x)=5 4x+7 f-1(x)=?答案inverse of 就是f(x)
To help sort out different cases, let f(x) and g(x) be two different trigonometric functions belonging to the set {sin(x), cos(x), tan(x)} and let f−1(y)f−1(y) and g−1(y)g−1(y) be their inverses.Evaluating Compositions of the Form f(f−1(y))f(f−1(y)...
Calculate {g}'(x), where g(x) is the inverse of f(x) = 7x + 9. Let g(x) be the inverse of the function f(x), and f'(x) = \frac{1}{1 + x^3}. Then g(x) is equal to . If g(x) = x/(1+x), then its inverse function g^-1(x) is: (a) x/(1+x) (b)...
Step 3: x = 4y - 7/4 [Interchange x and y.] Step 4: 4x = 4y - 7 [Multiply throughout by 4.] Step 5: 4x + 7 = 4y [Add 7 to both sides of the equation.] Step 6: 4x + 7/4 = y Step 7: The inverse function is y = 4x + 7/4. ...
What is the inverse of f(x) = 4x+3? Find the inverse of f(x) = 2(x - 3)^2 - 7, when x is greater than or equal to 3? what is the inverse of { F(x)=2(x+1)^3 } Find the inverse of f(x) = x^3 + 1.
Find the Inverse of f(x)=(x^3-2)/4○ f^(-1)(x)=4(x/2)^3○ f^(-1)(x)=√[3](4x+2)○ f^(-1)(x)=4√[3]x+2○f^(-1)(x)=4x^3+2 相关知识点: 试题来源: 解析 sountion f(x)=(x^2-2)/4 y=(x^3-2)/4 x=(y^3-2)/4 4x=y^3-2 y=√[3...
”x.”The raised−1−1is part of the notation. It is not an exponent; it does not imply a power of−1−1. In other words,f−1(x)f−1(x)does not mean1f(x)1f(x)because1f(x)1f(x)is the reciprocal offfand not the inverse. The “exponent-like” notation comes from ...
