inverse of f(x)=9x^2-10x

inverse

f (x) = 9 x^{2} - 10 x

\frac{5 + 9 x + 25}{9}, \frac{5 - 9 x + 25}{9}

Solution steps

y = 9 x^{2} - 10 x

Replace

x

with

y

x = 9 y^{2} - 10 y

Solve for

y, x = 9 y^{2} - 10 y

\frac{5 + 9 x + 25}{9}, \frac{5 - 9 x + 25}{9}

P (x) = - 15 x^{(2)} + 350 x - 2000

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

f (x) = \frac{2 x + 5}{x - 5}

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

g (x) = - 7 x + 3
