Question

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

Answer 1

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

so the answer is D

Answer 2

D is the answer I believe
