Which could be the function graphed below? On a coordinate plane, a curve opens down and to the right in quadrants 1 and 4. The curve starts on the y-axis in quadrant 4 and goes through the x-axis into quadrant 1. f (x) = StartRoot x EndRoot minus 2 f (x) = StartRoot x minus 3 EndRoot 1 f (x) = StartRoot 2x 4 EndRoot f (x) = StartRoot x 1 EndRoot 8

It depends on the subject for me. some exams are easier than others so i usually go through it and answer questions i know based on my general knowledge, then double check after. going through the lesson can a lot  because the exams can be  very lesson-specific, but sometimes they are ridiculously long so a lot of people don't take the time. i did find that, when i went through the lessons, i was making 100's on my exams vs strictly using + the internet and  i make 90's.

What are the questions
