Answer:

The inverse is


y =\sqrt{(((x-3)/(3)) ^(2)+5)/(2)}

Explanation:


y=3\sqrt{2x^(2) -5} + 3

To find the inverse of the function interchange the terms that's x becomes y and y becomes x

We have


x=3\sqrt{2y^(2)-5 }+3

Now solve for y

Move 3 to the other side of the equation


3\sqrt{2y^(2)-5 } = x-3

Divide both sides by 3

We have


\sqrt{2y^(2)-5 } =(x-3)/(3)

square both sides of the equation to remove the square root

That's


2y^(2)-5 = ((x-3)/(3)) ^(2)

Move 5 to the other side of the equation


2y^(2) = ((x-3)/(3)) ^(2)+5

Divide both sides by 2

We have


y^(2) = (((x-3)/(3)) ^(2)+5)/(2)

Find the square root of both sides

We have the final answer as


y =\sqrt{(((x-3)/(3)) ^(2)+5)/(2)}

Hope this helps you
