inverse of f(x)=8x^2

inverse

f (x) = 8 x^{2}

\frac{2 x}{4}, - \frac{2 x}{4}

Solution steps

y = 8 x^{2}

Replace

x

with

y

x = 8 y^{2}

Solve for

y, x = 8 y^{2}

\frac{2 x}{4}, - \frac{2 x}{4}

\frac{x - 8}{x + 8}

y = x^{2} - 6 x - 1

(2 - x) e^{- x}

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

\frac{5 x}{ln ( x ^{2} - 4 )}
