#### Answer:

Move all of the constants to one side of the equation with algebraic operations for general expression equal to x. This a function, not a single value.

#### Explanation:

You find ‘y’ for any given ‘x’ by putting x into the equation and solving it.
y = -3sqrt(x+4) + 6 ; y – 6 = -3sqrt(x+4) ; (y-6)/3 = sqrt(x+4) ; (y/3) – 2 = sqrt(x+4)
Now, square both sides:
(y^2)/9 – (4/3)y + 4 = x + 4
(y^2)/9 – (4/3)y = x#
