inverse of f(x)=(-2(x-4)+15)/(x-4)

inverse

f (x) = \frac{- 2 ( x - 4 ) + 15}{x - 4}

\frac{23 + 4 x}{x + 2}

Solution steps

y = \frac{- 2 ( x - 4 ) + 15}{x - 4}

Replace

x

with

y

x = \frac{- 2 ( y - 4 ) + 15}{y - 4}

Solve for

y, x = \frac{- 2 ( y - 4 ) + 15}{y - 4}

\frac{23 + 4 x}{x + 2}

7^{- x + 3}

- 1.19 x + 990

(x - 12)^{2}

x^{2} + 1

y = 5 x + 1
