inverse of f(x)=(4x)/(7+4x)

Solution

inverse

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

Solution

- \frac{7 x}{4 ( x - 1 )}

Solution steps

y = \frac{4 x}{7 + 4 x}

Replace

x

with

y

x = \frac{4 y}{7 + 4 y}

Solve for

y, x = \frac{4 y}{7 + 4 y}

- \frac{7 x}{4 ( x - 1 )}

Popular Examples

f(x)=sin(x)*cos(x)

f (x) = sin (x) \cdot cos (x)

domain of f(x)=-x^2+4x-3 domain

f (x) = - x^{2} + 4 x - 3
