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

inverse

f (x) = x - x

\frac{2 x + 1 + 4 x + 1}{2}, \frac{2 x + 1 - 4 x + 1}{2}

Solution steps

y = x - x

Replace

x

with

y

x = y - y

Solve for

y, x = y - y

\frac{2 x + 1 + 4 x + 1}{2}, \frac{2 x + 1 - 4 x + 1}{2}

f (x) = 7 x^{2} - 3, x \geq 0

\frac{3 s + 4}{s ^{2} + 9}

f (x) = (x^{3} - 4)^{\frac{1}{5}} + 4

4 x^{3} - 7

- 5 x^{2} + x
