inverse of f(x)=(2x+1)/(x+2)

Solution

inverse

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

Solution

\frac{1 - 2 x}{x - 2}

Solution steps

y = \frac{2 x + 1}{x + 2}

Replace

x

with

y

x = \frac{2 y + 1}{y + 2}

Solve for

y, x = \frac{2 y + 1}{y + 2}

\frac{1 - 2 x}{x - 2}

Popular Examples

intercepts of (x+1)(x-2)-2 intercepts

(x + 1) (x - 2) - 2

y = tan (x)

midpoint (-3,6),(5,-6)midpoint

(- 3, 6), (5, - 6)

intercepts of f(x)=-6x^2+384 intercepts

f (x) = - 6 x^{2} + 384

domain of f(x)=(x^2+2)/(3x^2-1)domain

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