inverse of f(3)= 9/(3-10x)-3

inverse

f (3) = \frac{9}{3 - 10 x} - 3

\frac{3 x}{10 ( x + 3 )}

Solution steps

y = \frac{9}{3 - 10 x} - 3

Replace

x

with

y

x = \frac{9}{3 - 10 y} - 3

Solve for

y, x = \frac{9}{3 - 10 y} - 3

\frac{3 x}{10 ( x + 3 )}

f (x) = 9 cos (\frac{1}{4} π x - π) - 2

8 x + 10 y = - 60

f (x) = 6 x - 8

f (x) = 5 x - 6

sin (3 x)
