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

Solution

inverse

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

Solution

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

Solution steps

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

Replace

x

with

y

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

Solve for

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

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

Popular Examples

domain of f(x)=(2x^2-x-4)/(x^2+9)domain

f (x) = \frac{2 x ^{2} - x - 4}{x ^{2} + 9}

inflection f(x)=2x^3-3x^2+8x-4 inflection points

f (x) = 2 x^{3} - 3 x^{2} + 8 x - 4

asymptotes of f(x)=tan(2x-2pi)asymptotes

f (x) = tan (2 x - 2 π)

line y+3=7(x-2)line

y + 3 = 7 (x - 2)

range of y=x^2-3 range

y = x^{2} - 3
