inverse of f(x)=-1/2 (x-1)^2+8

inverse

f (x) = - \frac{1}{2} (x - 1)^{2} + 8

- 2 x + 16 + 1, - - 2 x + 16 + 1

Solution steps

y = - \frac{1}{2} (x - 1)^{2} + 8

Replace

x

with

y

x = - \frac{1}{2} (y - 1)^{2} + 8

Solve for

y, x = - \frac{1}{2} (y - 1)^{2} + 8

- 2 x + 16 + 1, - - 2 x + 16 + 1
