Iseriously am having trouble with this problem! what is f-1(x).
the answer is but how do i get that answer? my personal answer was
me and explain how you came up with the actual answer. i greatly appreciate it and you!

see explanation

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = ← multiply both sides by (x + 1)

y(x + 1) = 2x - 3 ← distribute left side

xy + y = 2x - 3 ( subtract y from both sides )

xy = 2x - 3 - y ( subtract 2x from both sides )

xy - 2x = - 3 - y ← factor out x from each term on the left side

x(y - 2) = - 3 - y ← divide both sides by y - 2

x = factor out - 1 on numerator and denominator

x =

Change y back into terms of x, thus

(x) = =
