inverse of f(x)=x^2+2x-5

inverse

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

- 1 + x + 6, - x + 6 - 1

Solution steps

y = x^{2} + 2 x - 5

Replace

x

with

y

x = y^{2} + 2 y - 5

Solve for

y, x = y^{2} + 2 y - 5

- 1 + x + 6, - x + 6 - 1

a sy m pt o t es f (x) = (\frac{( 4 x )}{x ^{2} - 4 x + 3})

r an g e - x + 6

d o main x^{2} + 9

d o main f (x) = 2 x 3 x - 1

a sy m pt o t es f (x) = \frac{- 4 x ^{2} - 2 x + 1}{2 x + 3}
