inverse of f(x)=x^2-6x-8

inverse

f (x) = x^{2} - 6 x - 8

3 + x + 17, 3 - x + 17

Solution steps

y = x^{2} - 6 x - 8

Replace

x

with

y

x = y^{2} - 6 y - 8

Solve for

y, x = y^{2} - 6 y - 8

3 + x + 17, 3 - x + 17

f (x) = ln (2 x - 3) - ln (x + 5) + 1

f (x) = ln (3 x - 5) - ln (x + 9) + 5

f (x) = 47 x - 55

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