inverse of f(x)=(4x+3)/(1-9x)

inverse

f (x) = \frac{4 x + 3}{1 - 9 x}

- \frac{3 - x}{4 + 9 x}

Solution steps

y = \frac{4 x + 3}{1 - 9 x}

Replace

x

with

y

x = \frac{4 y + 3}{1 - 9 y}

Solve for

y, x = \frac{4 y + 3}{1 - 9 y}

- \frac{3 - x}{4 + 9 x}

f (x) = 2 tan (\frac{x}{2}) - 1

f (x) = x^{2} - 1

f (x) = - 2 (x + 3)^{2} - 1

(2 x - 8)^{\frac{2}{3}}

f (x) = \frac{( 3 x - 3 )}{x + 6}
