inverse of 800x-2x^2

inverse

800 x - 2 x^{2}

- \frac{- 800 + 640000 - 8 x}{4}, - \frac{- 800 - 640000 - 8 x}{4}

Solution steps

y = 800 x - 2 x^{2}

Replace

x

with

y

x = 800 y - 2 y^{2}

Solve for

y, x = 800 y - 2 y^{2}

- \frac{- 800 + 640000 - 8 x}{4}, - \frac{- 800 - 640000 - 8 x}{4}

f (x) = \frac{3 x}{( 7 x ^{2} + 16 )}

y = (e)^{x}

1 (0.5)^{x}

e^{- \frac{x ^{4}}{2}}

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