inverse of f(x)=35x^2+165x

inverse

f (x) = 35 x^{2} + 165 x

\frac{- 165 + 27225 + 140 x}{70}, \frac{- 165 - 27225 + 140 x}{70}

Solution steps

y = 35 x^{2} + 165 x

Replace

x

with

y

x = 35 y^{2} + 165 y

Solve for

y, x = 35 y^{2} + 165 y

\frac{- 165 + 27225 + 140 x}{70}, \frac{- 165 - 27225 + 140 x}{70}

f (x) = cot (x)

\frac{1}{z}

f (x) = \frac{1}{27} (5 y^{4} + 6 y^{2})

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

f (x) = \frac{x ^{2} + 2 x}{- 4 x + 8}
