inverse of f(x)=x^2+9x+26

inverse

f (x) = x^{2} + 9 x + 26

\frac{- 9 + 4 x - 23}{2}, \frac{- 9 - 4 x - 23}{2}

Solution steps

y = x^{2} + 9 x + 26

Replace

x

with

y

x = y^{2} + 9 y + 26

Solve for

y, x = y^{2} + 9 y + 26

\frac{- 9 + 4 x - 23}{2}, \frac{- 9 - 4 x - 23}{2}

f (x) = (3.8)

f (x) = \frac{( x + 4 )}{x + 10}

+ cos^{2} (x)

y = - x

f (x) = 2 \cdot arctan (x)
