inverse of f(x)=sqrt((7x+6)/(x-5))

inverse

f (x) = \frac{7 x + 6}{x - 5}

\frac{6 + 5 x ^{2}}{x ^{2} - 7}

Solution steps

y = \frac{7 x + 6}{x - 5}

Replace

x

with

y

x = \frac{7 y + 6}{y - 5}

Solve for

y, x = \frac{7 y + 6}{y - 5}

\frac{6 + 5 x ^{2}}{x ^{2} - 7}

f (x) = 7 (x^{\frac{1}{5}} - 10)

f (x) = - \frac{1}{2} x + 9

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

f (x) = x^{2} - 16 x + 20

f (x) = (x - 10)^{2}
