inverse of f(x)=x^2-2x-4

inverse

f (x) = x^{2} - 2 x - 4

1 + x + 5, 1 - x + 5

Solution steps

y = x^{2} - 2 x - 4

Replace

x

with

y

x = y^{2} - 2 y - 4

Solve for

y, x = y^{2} - 2 y - 4

1 + x + 5, 1 - x + 5

f (x) = - 2^{x - 5} + 4

cos (\frac{71}{6854})

\frac{( x - 2 )}{8}

k (x) = 2 x - 5

- \frac{x}{x ^{2} - 9}
