inverse of f(x)=2x^2+12x+11

inverse

f (x) = 2 x^{2} + 12 x + 11

\frac{- 12 + 8 x + 56}{4}, \frac{- 12 - 8 x + 56}{4}

Solution steps

y = 2 x^{2} + 12 x + 11

Replace

x

with

y

x = 2 y^{2} + 12 y + 11

Solve for

y, x = 2 y^{2} + 12 y + 11

\frac{- 12 + 8 x + 56}{4}, \frac{- 12 - 8 x + 56}{4}

f (x) = 2000 + 10 x

f (x) = (x - 3) 3 + 2

f (x) = (x + 3) 2

f (x) = \frac{- 7 x + 6}{10}

8 x
