jika f(x) = 2x-1/2x-3 maka nilai dari f-¹ (3) adalah? tolong respon cepattt

f(x) = (2x - 1)/(2x - 3)

f^-1 (2x - 1)/(2x - 3) = x
f^-1 (3) = x

(2x - 1)/(2x - 3) = 3
2x - 1 = 3(2x - 3)
2x - 6x = 1 - 9
-4x = -8
x = 2

f^-1 (3) = x
f^-1 (3) = 2

Bab Fungsi Komposisi

f(x) = (ax + b)/(cx + d)
f^-1 (x) = (-dx + b)/(cx - a)

f(x) = (2x - 1)/(2x - 3)
f^-1 (x) = (3x - 1)/(2x - 2)
f^-1 (3) = (3 . 3 - 1)/(2 . 3 - 2)
f^-1 (3) = (9 - 1)/(6 - 2)
f^-1 (3) = 8/4
f^-1 (3) = 2
