inverse of x^2+2x

Solution

inverse

x^{2} + 2 x

Solution

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

Solution steps

y = x^{2} + 2 x

Replace

x

with

y

x = y^{2} + 2 y

Solve for

y, x = y^{2} + 2 y

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

Popular Examples

domain of f(x)= x/(6x+25)domain

f (x) = \frac{x}{6 x + 25}

range of (x^2)/(x^2+1)range

\frac{x ^{2}}{x ^{2} + 1}

range of sqrt(2x+4)range

2 x + 4

f(x)=sqrt(1/(x-1)+1)

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

range of 4+7sqrt(25-x^2)range

4 + 7 25 - x^{2}
