What is f^-1(3) when f(x)=2x-1? 2009-01-03 From Peter:how do you do functions like f^-1(3) when f(x)=2x-1?Answered by Penny Nom. Inverses of Quadratic Functions 2007-10-11 From Elliot:I'm a special education tchr trying to demonstrate how to find the inverse (using algebra) of quadratic functions. Any help would be greatly appreciated.Answered by Steve La Rocque and Harley Weston. y = log(x) + x. Solve for x. 2005-08-26 From Alain:I have the following equation: y = ln(x) + x How do I solve for x? Answered by Penny Nom. An inverse 2004-09-09 From Hillary:I cannot figure out the inverse of this function. f(x)= 1/2x -1Answered by Penny Nom. Differentiating inverses 2002-11-20 From Amy:f(x)= x3+x+1, a=1 find g'(a) (g = f -1). I am having trouble finding g(a).Answered by Penny Nom. Range of a function 2000-11-21 From David Bell:Given a rational function such as f(x) = (8x-3)/(4x-1). How can the range be found.Answered by Penny Nom. Inverses of functions 1999-11-01 From Leanne Hickey:Let f(x) = 2x2 -3x + 2. Find f-1(4) given the fact that f(2) = 4. So the question is finding the inverse of 4, he said it's easier than it looks.Answered by Penny Nom.
