inverse of f(x)=(7x)/(x+3)

Solution

inverse

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

Solution

- \frac{3 x}{x - 7}

Solution steps

y = \frac{7 x}{x + 3}

Replace

x

with

y

x = \frac{7 y}{y + 3}

Solve for

y, x = \frac{7 y}{y + 3}

- \frac{3 x}{x - 7}

Popular Examples

amplitude of 1/6 cos(7x)amplitude

\frac{1}{6} cos (7 x)

monotone f(x)=(x^2)/2+1/x monotone intervals

f (x) = \frac{x ^{2}}{2} + \frac{1}{x}

slope of 4x+6y=-5 slope

4 x + 6 y = - 5

y = 5^{x}

extreme f(x)=(12*x^2-60x+44)extreme points

f (x) = (12 \cdot x^{2} - 60 x + 44)
