inverse of g(x)=x^2-5x-6

inverse

g (x) = x^{2} - 5 x - 6

\frac{5 + 4 x + 49}{2}, \frac{5 - 4 x + 49}{2}

Solution steps

y = x^{2} - 5 x - 6

Replace

x

with

y

x = y^{2} - 5 y - 6

Solve for

y, x = y^{2} - 5 y - 6

\frac{5 + 4 x + 49}{2}, \frac{5 - 4 x + 49}{2}

f (x) = \frac{- 2 x + 7}{x}

y = \frac{2}{x}

f (x) = 625 (1 - \frac{x}{50})^{2}

\frac{2}{x ^{2}}

f (x) = x + 4 - 9
