inverse of f(x)=x^2+3x+2

inverse

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

\frac{- 3 + 4 x + 1}{2}, \frac{- 3 - 4 x + 1}{2}

Solution steps

y = x^{2} + 3 x + 2

Replace

x

with

y

x = y^{2} + 3 y + 2

Solve for

y, x = y^{2} + 3 y + 2

\frac{- 3 + 4 x + 1}{2}, \frac{- 3 - 4 x + 1}{2}

f (x) = (x - 1)^{2} - 9

(2, - 8), (7, - 4)

f (x) = \frac{∣ x ∣}{x}

\frac{x ^{2} + x - 12}{x - 3}

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