inverse of f(x)=sqrt(((12-4x))/((12-x)))

inverse

f (x) = \frac{( 12 - 4 x )}{( 12 - x )}

\frac{12 - 12 x ^{2}}{- x ^{2} + 4}

Solution steps

y = \frac{12 - 4 x}{12 - x}

Replace

x

with

y

x = \frac{12 - 4 y}{12 - y}

Solve for

y, x = \frac{12 - 4 y}{12 - y}

\frac{12 - 12 x ^{2}}{- x ^{2} + 4}

\frac{z ^{2}}{( z - 1 ) ( z - 3 )}

2^{x^{2} - 1}

11 cos (2 x) + 5

\frac{2 s + 3}{s ( 2 s + 1 )}
