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

inverse

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

- 3 + x + 17, - x + 17 - 3

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, - x + 17 - 3

f (x) = 9.5 x^{2} - x + 2.6

\frac{x ^{3}}{3} + 2 x^{2} + 4 x - 1

f (x) = \frac{5 x}{2 x + 3}

f (x) = x^{3} - 3 x + 2

f (x) = - x^{6}, x \geq 0
