To find the inverse of a function, replace every x in the equation with a y, and replace every y in the equation with an x:

Add 9 to both sides:

Square root both sides to get y by itself:

This equation can be simplified by taking the square root of 9 out of the root:


The inverse of this function is
y = 3 + √x.
