"show that if f has an assignment which satisfies sat"

I’m not positive on what you’re asking but I’ll give my answer to my best ability.

If you’re talking about the SAT score range, it is scored between 400 and 1600 for your total score, and 200-800 for each of your two subscores. One subscore is for Math, and then one subscore is your combined Reading and Writing scores to make one Evidence-Based Reading and Writing score. If that makes any sense. I hope I’ve helped and if you’ve got a different question there is always the comment box!
