inverse of f(x)=-2x^2-8x+4

inverse

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

- \frac{8 + - 8 x + 96}{4}, - \frac{8 - - 8 x + 96}{4}

Solution steps

y = - 2 x^{2} - 8 x + 4

Replace

x

with

y

x = - 2 y^{2} - 8 y + 4

Solve for

y, x = - 2 y^{2} - 8 y + 4

- \frac{8 + - 8 x + 96}{4}, - \frac{8 - - 8 x + 96}{4}

0.3234 ln (x) + 0.4893
