Jawab:f⁻¹(x) = ⅓(x-5)
Penjelasan . . . :Diketahui:f(x) = 3x + 5
Ditanya:f⁻¹(x)
f(x) = 3x + 5y = 3x + 5ubah posisi x dan yx = 3y + 53y = x - 5y = ⅓(x-5)Lalu y ubah ke f⁻¹(x)f⁻¹(x) = ⅓(x-5)

Jawab:
f⁻¹(x) = ⅓(x-5)
Penjelasan . . . :
Diketahui:
f(x) = 3x + 5
Ditanya:
f⁻¹(x)
f(x) = 3x + 5
y = 3x + 5
ubah posisi x dan y
x = 3y + 5
3y = x - 5
y = ⅓(x-5)
Lalu y ubah ke f⁻¹(x)
f⁻¹(x) = ⅓(x-5)
