tolong beserta caranya

jawabannya yang -1
maaf kalo salah

f(x + 3) = (x - 2)/(x + 4)
Misal x + 3 = a => x = a - 3
f(a) = (a - 3 - 2)/(a - 3 + 4)
f(a) = (a - 5)/(a + 1)
f(x) = (x - 5)/(x + 1)
f^-1(x) = (-x - 5)/(x - 1)
f^-1(-2) = (-(-2) - 5)/(-2 - 1) = -3/-3 = 1

g(x) = 2x^2 - 3

(g o f^-1)(-2) = g(f^-1(-2)) = g(1) = 2(1)^2 - 3 = 2 - 3 = -1
