Here, we're given a graph of a function, and we're asked to approximate the integral from 0 to 0 .5 of f of x.
00:07
Well, that just means what is the area under the curve? so if i go to 0 .5 and find my curve that goes to here, and then from 0, it's this area right here.
00:19
Notice this is almost a rectangle.
00:21
Like i could finish this out and say, okay, it's a rectangle, but there's a little too much if that's a rectangle.
00:28
So the rectangle would be an area of 0 .5 times 100, because that's the height of this curve.
00:37
So i know my answer is just a little bit less than 50.
00:41
So if i look at the options, one of them is 49 .95, and there's another one that's 46 .2.

Hmm...
