A lot of graphs on QR?

Did you guys who have taken the DAT encounter many problems involving "find the area shaded in the graph" or "find the formula that represents the shaded region of the graph" type problems on the real QR section of the DAT?

I hope. Those are some of the easiest questions you can get... lol

If you find them so easy, perhaps you could break them down for me? I haven't taken a math class in 4 years and these aren't coming back so easily. 🙂

I also would not mind, math has never been one of my strengths, and I am willing to do anything to improve that!

Maybe 1 question on my exam, if that.

I actually got 2 last year, thankfully they didn't ask me to use the washer method on it 😛

But in all seriousness, it's not common and I think you can get away with not studying for it if you're worried about it.

Isn't that like elementary school math? Just convert the shades into triangles and squares sum up their respective areas. If they're giving you curves, then integral. I highly doubt they're testing you guys calculus QR currently

All you have to do is plug in a point, find if the relationship is true = shaded, if false = non shaded.

Thanks (most of you) for your responses. I understand the obvious ones, but questions like the following trip me up:

Which of the following expressions represents the shaded area in the graph below?

Answer was:

I was supposed to realize that the shaded part was greater than an exponential function but less than a straight line. I get that after reviewing the answer. But are they ever going to ask you to calculate this instead of just eliminating answer choices?

I didn't get anything as close to complex as that.

I got basic physics-y kinematic-type problems i.e. if Nancy walks 3 m/s for 100 meters, stops for 10 seconds, and runs 5 m/s for 200 meters, how much distance did she cover?

I got no questions where they gave you 2 equations and asked you to find something in between.

That is a relief 🙂. Thank you very much!

You won't get one as complex as that. But, again, plug in points and you'll easily arrive at the answer.

They won't ask you for the equations themselves, most likely.
