Answer:

The inverse relation is:

[tex]y=4 \pm \sqrt{x}[/tex]

Step-by-step explanation:

We need to solve for x.

Useful formula: (x-y)^2=x^2-2xy+y^2.

[tex]y=x^2-8x+16[/tex]

[tex]y=(x-4)^2[/tex]

Now, take the square root of both sides:

[tex]\pm \sqrt{y}=x-4[/tex]

Add 4 on both sides:

[tex]4 \pm \sqrt{y}=x[/tex]

Interchange x and y:

[tex]4 \pm \sqrt{x}=y[/tex]

The inverse relation is:

[tex]y=4 \pm \sqrt{x}[/tex]
