inverse of f(x)=3sqrt(x)-4

inverse

f (x) = 3 x - 4

\frac{x ^{2}}{9} + \frac{8 x}{9} + \frac{16}{9}

Solution steps

y = 3 x - 4

Replace

x

with

y

x = 3 y - 4

Solve for

y, x = 3 y - 4

\frac{x ^{2}}{9} + \frac{8 x}{9} + \frac{16}{9}

f (x) = \frac{10}{x - 6}

f (x) = 3 - x - 2 + x

y = - 3 x + 9

2 x - y = 4

f (x) = x^{3} + 6 x^{2} - 15 x
