inverse of y=2pix^2+8pix

inverse

y = 2 π x^{2} + 8 π x

\frac{- 8 π + 64 π ^{2} + 8 π x}{4 π}, \frac{- 8 π - 64 π ^{2} + 8 π x}{4 π}

Solution steps

y = 2 π x^{2} + 8 π x

Replace

x

with

y

x = 2 π y^{2} + 8 π y

Solve for

y, x = 2 π y^{2} + 8 π y

\frac{- 8 π + 64 π ^{2} + 8 π x}{4 π}, \frac{- 8 π - 64 π ^{2} + 8 π x}{4 π}

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

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

3 cos (2 x)

\frac{72}{x}
