inverse of f(x)=(15-4x)/(4-x)

inverse

f (x) = \frac{15 - 4 x}{4 - x}

\frac{15 - 4 x}{- x + 4}

Solution steps

y = \frac{15 - 4 x}{4 - x}

Replace

x

with

y

x = \frac{15 - 4 y}{4 - y}

Solve for

y, x = \frac{15 - 4 y}{4 - y}

\frac{15 - 4 x}{- x + 4}

f (x) = - (x + 5)^{2} - 4

3 tan (2 x - \frac{π}{3})

f (x) = \frac{6 x + 6}{5 x - 6}

f (s) = 2 - 3 s^{(2)}

- 1 + x
