Find the minimum value of the function

Just by looking at it, the smallest I can see is 501, when x=-1.
No idea how to do it "properly" though.
Why did the vector cross the road?
It wanted to be normal.

If x ≠ 1,
Indeed, as f(1) isnt the mininum value, you might as well use this formula. Also it appears that f(x) is always positive, so you can probably ignore the modulus sign as well.
I then used differentiation and verified that f(−1) is the minimum value. Well, maybe theres a less complicated way to do this.
