Answer:

  f⁻¹(x) = √((3 -x)/3)

Step-by-step explanation:

A function gives you a y-value for each value of x.

  y = f(x)

__

An inverse function tells you the x value that produced a given y-value. It is the solution to the equation ...

  x = f(y)

So, we want to find y for ...

  x = -3y² +3

  x -3 = -3y² . . . . . . . . . . . subtract 3

  (x -3)/-3 = y² . . . . . . . . . divide by -3

  √((x -3)/-3) = y . . . . . . . take the square root.

The requirement for x > 0 in the original function means y > 0 for the inverse function. That is why we use the positive square root.

This can be simplified a little bit to remove the minus sign from the denominator.

  f⁻¹(x) = √((3 -x)/3)

__

The graph plots the function and its inverse. They are reflections of each other over the line y=x. (That's one way you can tell you have the correct inverse function.)
