inverse of f(x)=x^2-8x+20

inverse

f (x) = x^{2} - 8 x + 20

4 + x - 4, 4 - x - 4

Solution steps

y = x^{2} - 8 x + 20

Replace

x

with

y

x = y^{2} - 8 y + 20

Solve for

y, x = y^{2} - 8 y + 20

4 + x - 4, 4 - x - 4

1 + e^{x}

f (x) = \frac{4 - 2 x}{3 + x}

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

\frac{2}{3} (x - 5)

f (x) = \frac{x ^{3} + 1}{3}
