inverse of f(x)=(15x+50)/(x+5)

inverse

f (x) = \frac{15 x + 50}{x + 5}

\frac{50 - 5 x}{x - 15}

Solution steps

y = \frac{15 x + 50}{x + 5}

Replace

x

with

y

x = \frac{15 y + 50}{y + 5}

Solve for

y, x = \frac{15 y + 50}{y + 5}

\frac{50 - 5 x}{x - 15}

f (x) = x^{2} + 4

f (x) = \frac{9}{x ^{2} - 144}

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

m = - 0.5, (8, 14)

(- 5, 5), (3, - 5)
