Find the inverse of the function.

y = -3/x+4

a) x = 4y-3/y
b) y = 4x/3
c) y = x-3/x
d) y = -4x-3/x

Respuesta :

D is the answer I believe

[tex]f(x) = \frac{ax + b}{cx + d} \\ {f}^{ - 1}(x) = \frac{ - dx + b}{cx - a} \\ \\ y = \frac{0x - 3}{x + 4} \\ {y}^{ - 1} = \frac{ - 4x - 3}{x} [/tex]

so the answer is D
