Jika fungsi f(x) = 2x + 3/ x-5 X ≠ 5 dan g(x) = 3x + 1 Maka (gof)^-1 (x) =... Sertakan pembahasannya yaa terimakasihh

p(x) = (ax + b) / (cx + d)
p⁻¹ (x) = (-dx + b) / (cx - a)

(gof) (x) = g (f(x))
              = g ((2x + 3) / (x - 5))
              = 3 ((2x + 3) / (x - 5)) + 1
              = (6x + 9 + x - 5)/(x - 5)
              = (7x + 4) / (x - 5)

(gof)⁻¹ (x) = (5x + 4) / (x - 7)
