inverse of f(x)=-3(x-1)^2+9,x<= 1

inverse

f (x) = - 3 (x - 1)^{2} + 9, x \leq 1

- \frac{x - 9}{3} + 1, - - \frac{x - 9}{3} + 1

Solution steps

y = - 3 (x - 1)^{2} + 9

Replace

x

with

y

x = - 3 (y - 1)^{2} + 9

Solve for

y, x = - 3 (y - 1)^{2} + 9

- \frac{x - 9}{3} + 1, - - \frac{x - 9}{3} + 1
