inverse of f(x)=5x(6-x)

inverse

f (x) = 5 x (6 - x)

- \frac{- 30 + 900 - 20 x}{10}, - \frac{- 30 - 900 - 20 x}{10}

Solution steps

y = 5 x (6 - x)

Replace

x

with

y

x = 5 y (6 - y)

Solve for

y, x = 5 y (6 - y)

- \frac{- 30 + 900 - 20 x}{10}, - \frac{- 30 - 900 - 20 x}{10}

f (x) = 9^{x}

f (x) = \frac{3}{2} x + 6

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

y = 5 x + 8

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