inverse of 6.75sqrt(x)+12

inverse

6.75 x + 12

\frac{16 x ^{2}}{729} - \frac{128 x}{243} + \frac{256}{81}

Solution steps

y = 6.75 x + 12

Replace

x

with

y

x = 6.75 y + 12

Solve for

y, x = 6.75 y + 12

\frac{16 x ^{2}}{729} - \frac{128 x}{243} + \frac{256}{81}

f (x) = \frac{3}{x ^{2} - 1}

f (x) = 13 x + 3

f (x) = 13 x + 8

f (x) = \frac{1}{6} x - \frac{1}{3}

g (x) = \frac{x + 5}{x - 4}
