# Find the Inverse

(x)=√2x+9

## I'm going to assume that the only thing under the square root symbol is the 2.

Write your equation with a "y" on the left side:

y = √2x+9

And then to find the inverse, you first just switch the x's and the y's, and get,

x = √2y+9

And then you solve this for y,

Flip it around,

√2y+9 = x

Move the 9 over to the right side,

√2y = x - 9

Divide both sides by √2, which will just leave a y on the left side,

y = (x - 9)/√2
