Question
2x−72x+9 , find f, to the power minus 1 , left bracket, x, right bracketf −1 (x).AnswerAttempt 3 out of 8
Solution
It seems like you're asking for the inverse of the function f(x) = 2x - 7/(2x + 9). Here are the steps to find the inverse:
-
Replace f(x) with y. So, the equation becomes y = 2x - 7/(2x + 9).
-
Swap x and y. The equation becomes x = 2y - 7/(2y + 9).
-
Solve for y. This is the tricky part. You'll need to do some algebraic manipulation to isolate y.
Unfortunately, the equation you've given is a bit complex and it's not clear how to solve for y in step 3. Could you please check the equation?
