1. Tentukan invers dari fungsi f(x) = 2x + 3.

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

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

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

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

2. Jika f(x) = x^2 - 4, cari inversnya.

f^(-1)(y) = √(y - 4)

f^(-1)(y) = y - 4

f^(-1)(y) = ±√(y + 4)

f^(-1)(y) = -√(y + 4)

4. Diberikan fungsi f(x) = 1/(x - 2), cari inversnya.

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

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

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

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

5. Jika f(x) = 5x + 7, tentukan f^-1(x).

f^-1(x) = 5x - 7

f^-1(x) = (x - 7) / 5

f^-1(x) = 5(x - 7)

f^-1(x) = (x + 7) / 5

6. Temukan invers dari fungsi f(x) = 4x^3 + 1.

f^(-1)(x) = ((x - 1)/4)^(1/3)

f^(-1)(x) = (x^3 + 1)/4

f^(-1)(x) = (x + 1)/4

f^(-1)(x) = 4(x - 1)^(1/3)
