inverse of f(x)=-2x^2-4x+6

inverse

f (x) = - 2 x^{2} - 4 x + 6

- \frac{4 + - 8 x + 64}{4}, - \frac{4 - - 8 x + 64}{4}

Solution steps

y = - 2 x^{2} - 4 x + 6

Replace

x

with

y

x = - 2 y^{2} - 4 y + 6

Solve for

y, x = - 2 y^{2} - 4 y + 6

- \frac{4 + - 8 x + 64}{4}, - \frac{4 - - 8 x + 64}{4}

\frac{x + 5}{x - 3}

f (x) = e^{x} - \frac{1}{e ^{x}}

f (x) = 2 x^{2} - 4 x + 7

f (x) = 3 x^{\frac{1}{5}} - 4

f (x) = 4 x - 13
