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

inverse

f (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) = 10 - 2 x^{\frac{1}{2}}

f (x) = 9 x^{4}

f (x) = - 4 - 2 x + 1 - 2

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

f (x) = 3 - 0.5 2 x + 4
