inverse of f(x)=(1-4x)/(3x+7)

inverse

f (x) = \frac{1 - 4 x}{3 x + 7}

\frac{1 - 7 x}{3 x + 4}

Solution steps

y = \frac{1 - 4 x}{3 x + 7}

Replace

x

with

y

x = \frac{1 - 4 y}{3 y + 7}

Solve for

y, x = \frac{1 - 4 y}{3 y + 7}

\frac{1 - 7 x}{3 x + 4}

f (x) = x + 6 - \frac{7 - x}{x}

f (x) = lo g_{4} (x - 1)

x^{3} - 27

f (x) = 3 x^{4} - 4 x^{3} + 6

1 + x
