inverse of f(x)=(sqrt(x))/5+2

inverse

f (x) = \frac{x}{5} + 2

25 x^{2} - 100 x + 100

Solution steps

y = \frac{x}{5} + 2

Replace

x

with

y

x = \frac{y}{5} + 2

Solve for

y, x = \frac{y}{5} + 2

25 x^{2} - 100 x + 100

\frac{3 x - 1}{2 x + 1}

f (x) = ln (10 x + e)

f (x) = \frac{8 x + 1}{x - 7}

\frac{3 - 2 x}{x + 4}

2^{x - 3} - 5
