inverse of f(x)=((x+3))/((x-8))

inverse

f (x) = \frac{( x + 3 )}{( x - 8 )}

\frac{3 + 8 x}{x - 1}

Solution steps

y = \frac{x + 3}{x - 8}

Replace

x

with

y

x = \frac{y + 3}{y - 8}

Solve for

y, x = \frac{y + 3}{y - 8}

\frac{3 + 8 x}{x - 1}

f (x) = 5 x - 4 y = 20

- \frac{2}{3}

y = 3 x

f (x) = (x - 5)^{2}, x \geq 5

y = 3 x - 4
