inverse of f(x)=123*x+18\mod 256

inverse

f (x) = 123 \cdot x + 18 mod 256

Solution steps

y = 123 x + 18 mod 256

Replace

x

with

y

x = 123 y + 18 mod 256

Solve for

y, x = 123 \cdot y + 18 mod 256

f (x) = (\frac{1}{3}) x

f (x) = 3^{x - 3}

x^{4} + 3

f (x) = 5 + x + 4 2 x + 1

f (x) = 2 - e^{(- \frac{1}{3} y)}
