inverse of f(x)=-0.5x^2+1.5x

inverse

f (x) = - 0.5 x^{2} + 1.5 x

- \frac{- 3 + - 8 x + 9}{2}, \frac{- 8 x + 9 + 3}{2}

Solution steps

y = - 0.5 x^{2} + 1.5 x

Replace

x

with

y

x = - 0.5 y^{2} + 1.5 y

Solve for

y, x = - 0.5 y^{2} + 1.5 y

- \frac{- 3 + - 8 x + 9}{2}, \frac{- 8 x + 9 + 3}{2}
