inverse of f(x)=x-2sqrt(x)

inverse

f (x) = x - 2 x

x + 2 + 2 x + 1, x + 2 - 2 x + 1

Solution steps

y = x - 2 x

Replace

x

with

y

x = y - 2 y

Solve for

y, x = y - 2 y

x + 2 + 2 x + 1, x + 2 - 2 x + 1

y + 3

f (x) = \frac{3 x - 4}{2 x - x}

f (x) = lo g_{7} (x)

f (x) = 6 x^{2} - 5 x + 8

15 x^{2} - 7
