inverse of f(x)=x^2+6x+8

inverse

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

- 3 + x + 1, - x + 1 - 3

Solution steps

y = x^{2} + 6 x + 8

Replace

x

with

y

x = y^{2} + 6 y + 8

Solve for

y, x = y^{2} + 6 y + 8

- 3 + x + 1, - x + 1 - 3

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

f (x) = - x^{2} + 5 x - 4

f (x) = \frac{x}{6} + 2

16

f (x) = \frac{3 x - 1}{x - 2}
