If f(x)=(3x-1)/2 and "f-1" is the inverse of f,what is the value of "f-1(3)"?

If g(f(x))=2x+1 and f(x)=1/4x-1,then g(x)= If f(x)=4x+1 and g(x)=x^2-3x+1,then (f+g)(-2)=? If f(x)=(3x-1)/2 and f-1 is the inverse of f,what is the value of f-1(3)? It is given that f(x-1)= -2(x-1)^3 + (x-1)^2 +x-1 and g(x)=2x^3 - x^2 - x +k.If..It is given that f(x-1)= -2(x-1)^3 + (x-1)^2 +x-1 and g(x)=2x^3 - x^2 - x +k.If the graph of y= g(x) is obtained by translating the graph of y=f(x) upwards by 3 units,an Find out F(1)=?If dy/dx =1/2x,and f(e)=0 f(x)=x^2,and if h is not zero,then f(x+h)-f(x)/h=?美国的数学题, if tan(1/2)x=2/5 and 关于一题SAT数学题If f(x)=x^3+1 and of f^(-1)（x) is the inverse function of f,what is f^(-1)(4)? 答案是1.44 求详细解答! 谢谢谢!inverse function 是什么? if f(x) is a linear function such that f(2)=5 and f(4)=13,f(x)=? 1.given the function f(x) = x*2 -4x -5,find the values of:a) f(k-2) b) f(x*2) - x*2 f(1)2.given two functions f(x) = x*2 -3 and g(x) = 3x-4,find the values of:a) f(k+1) -g(k-1) b) f(g(x)) c) g(f(x))3.let f(x) = 1/1-x,finda) f(f(x)) b) f(f(f(x))) c) f 已知f(x)满足2f(x)+f(1/x)=3x,求f(x) F(X)满足F(x)+2f(x分之1)=3X,求f(x) 已知f(x)满足2f(x)+f(1/x)=3x,求f(x)? 已知f(x)满足2f(x)+f(-x)=-3x+1,求f(x) 已知f(x)满足f(x)+2f(1/x)=3x,求f(x) , 1.Does formula f(x)=1/(x²-2) define a function f:R->R?A function Z->R?2.If there are 2187 function f:A->B and |B|=3.What is |A|?3.Give an example of a function f:A->B and A1,A2 in the A for which f(A1∩A2) ≠ f(A1)∩f(A2)4.If A={1,2,3,4,5} an If f(x)=log(x).write out the domain and range of the function. 2道英文的数学题,1)If f (x) = ax^2 + bx + c; f (2012) = 0; f (2010) = 0 and f (0) = 8,088,240then for what value of x is f a maximum?What is the maximum value of f 2)What is the remainder when2011x^2010+ 2009x^1005+ 2005x^201+ 2003x^67+ 2001 is
