inverse of f(x)=(7x-8)/(2x+9)

inverse

f (x) = \frac{7 x - 8}{2 x + 9}

\frac{- 8 - 9 x}{2 x - 7}

Solution steps

y = \frac{7 x - 8}{2 x + 9}

Replace

x

with

y

x = \frac{7 y - 8}{2 y + 9}

Solve for

y, x = \frac{7 y - 8}{2 y + 9}

\frac{- 8 - 9 x}{2 x - 7}

cos (9 0^{\circ})

f (x) = \frac{2 x + 3}{3 x - 4}

f (x) = \frac{5}{7} x + 4

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

y = - 3 x^{2} + 100 x + 1
