inverse of f(x)=x^2+7x+6

inverse

f (x) = x^{2} + 7 x + 6

\frac{- 7 + 4 x + 25}{2}, \frac{- 7 - 4 x + 25}{2}

Solution steps

y = x^{2} + 7 x + 6

Replace

x

with

y

x = y^{2} + 7 y + 6

Solve for

y, x = y^{2} + 7 y + 6

\frac{- 7 + 4 x + 25}{2}, \frac{- 7 - 4 x + 25}{2}

f (x) = 3 (x + 1)^{2} + 2

f (x) = \frac{20 + 0.4 x}{100 + x}

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

y = \frac{x + 1}{x - 1}

f (x) = \frac{8 x}{3 x - 4}
