inverse of y=e^x+2e^{2x}

inverse

y = e^{x} + 2 e^{2 x}

ln (\frac{- 1 + 1 + 8 x}{4}), ln (\frac{- 1 - 1 + 8 x}{4})

Solution steps

y = e^{x} + 2 e^{2 x}

Replace

x

with

y

x = e^{y} + 2 e^{2 y}

Solve for

y, x = e^{y} + 2 e^{2 y}

ln (\frac{- 1 + 1 + 8 x}{4}), ln (\frac{- 1 - 1 + 8 x}{4})

f (x) = ∣ x ∣ + 1

f (x) = \frac{1}{( x + 4 ) ^{2}}

x^{2} - y = 6

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

x^{2} - 6 x + 5
