Best ResponseYou've already chosen the best response.0I know that something to the ^1 power is basically the recipricol.. like 5^1 would be 1/5 but how would I do the fraction in this problem?

Best ResponseYou've already chosen the best response.0f^1(x) is not the same as 1/f(x) The easiest method to solve this is to write y instead of f(x). Then you solve the equation for x in terms of y. f(x) = (4x+1)/3 y=(4x+1)/3 3y=4x+1 . . . x=(3y1)/4 f^1(x)=(3x1)/4 f^1(3)=2

Best ResponseYou've already chosen the best response.0Equivalently, you can plug in y = 3 and solve for x to get the same answer y=(4x+1)/3 3=(4x+1)/3 ... ... ... x = 2

Best ResponseYou've already chosen the best response.0The notation \(\Large f^{1}(x)\) means "f inverse" or "the inverse of f(x)" like jualbafer wrote, it is NOT the same as \(\LARGE \frac{1}{f(x)}\) yes it's confusing because the negative one exponent has 2 different meanings
