inverse of f(x)= 2/3 (x-1)^2-3

inverse

f (x) = \frac{2}{3} (x - 1)^{2} - 3

\frac{3 x + 9}{2} + 1, - \frac{3 x + 9}{2} + 1

Solution steps

y = \frac{2}{3} (x - 1)^{2} - 3

Replace

x

with

y

x = \frac{2}{3} (y - 1)^{2} - 3

Solve for

y, x = \frac{2}{3} (y - 1)^{2} - 3

\frac{3 x + 9}{2} + 1, - \frac{3 x + 9}{2} + 1
