inverse of f(x)=-9sqrt(x-8)+5

inverse

f (x) = - 9 x - 8 + 5

\frac{x ^{2} - 10 x + 25}{81} + 8

Solution steps

y = - 9 x - 8 + 5

Replace

x

with

y

x = - 9 y - 8 + 5

Solve for

y, x = - 9 y - 8 + 5

\frac{x ^{2} - 10 x + 25}{81} + 8

f (x) = lo g_{\frac{1}{2}} (x)

f (x) = x^{2} - x + 1

(- 4, 3), (2, - 5)

\frac{1}{x - 3}, x = 7

\frac{( \frac{x}{x + 4} )}{( x ^{3} )}
