inverse of f(x)=-5sqrt(x-5),x>= 5

inverse

f (x) = - 5 x - 5, x \geq 5

\frac{x ^{2}}{25} + 5

Solution steps

y = - 5 x - 5

Replace

x

with

y

x = - 5 y - 5

Solve for

y, x = - 5 y - 5

\frac{x ^{2}}{25} + 5

\frac{8 x - 3}{x}

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

\frac{2}{s ^{2} + 2 s - 13}

\frac{x + 8}{3}

f (x) = 14 + 3 x
