inverse of y=x^2+x-1

Solution

inverse

y = x^{2} + x - 1

Solution

\frac{- 1 + 4 x + 5}{2}, \frac{- 1 - 4 x + 5}{2}

Solution steps

y = x^{2} + x - 1

Replace

x

with

y

x = y^{2} + y - 1

Solve for

y, x = y^{2} + y - 1

\frac{- 1 + 4 x + 5}{2}, \frac{- 1 - 4 x + 5}{2}

Popular Examples

parity f(x)=x^5+3x^4 parity

f (x) = x^{5} + 3 x^{4}

range of 1/x+3 range

\frac{1}{x} + 3

domain of f(x)=|x-4|domain

f (x) = ∣ x - 4 ∣

asymptotes of f(x)=(x^2+2)/(x-1)asymptotes

f (x) = \frac{x ^{2} + 2}{x - 1}

intercepts of f(x)=7tan(0.4x)intercepts

f (x) = 7 tan (0.4 x)
